what could cause an error DNA in replication

Answers

Answer 1

NOTICE: There are attachments attached to this answer that is mentioned  in each paragraph!

We frequently see DNA replication as a well-organized, methodical process, much like a production line. It's not. For the DNA polymerase to read it, the DNA must not lie in a straight line and must be in motion, not static. It is curled and twisted. First, realize that this is a molecular issue. Bacteria lack neurons, cannot "think," and cannot make decisions. Everything is a chemical reaction, and chemical reactions frequently depend on one concentration's osmotic pressure being higher than another, both inside the cell and outside. Even at that level, there is a lot of "nothing," albeit nothing is empty. For a better understanding of the environment, picture a cell as a large room filled with balls of all sizes. Each ball has a unique form and isn't spherical; some balls fit together flawlessly while others don't. This is the easiest way to conceptualize the universe of molecular chemistry. There is never "nothing" other than in space when you push your way through layers upon layers of free oxygen, free nitrogen, helium, carbon dioxide, hydrogen dioxide, argon, methane, etc. when you walk through what we term "air."

Replication mistakes happen. Sometimes DNA polymerase enzymes add the incorrect nucleotide, too many, or too few nucleotides to a sequence. Or the DNA polymerase gets looped on the same strand, adding a few codons in a repetition before the strand slips away and it continues, or there is a tangle of crossing DNA and it jumps to the incorrect thread and back (or never), etc. In order to ensure that the bases added to a developing strand are appropriately matched with their complements, DNA polymerase enzymes are quite picky about the nucleotides they choose to use. However, these enzymes do make errors. Specifically, at a rate of around 1 per 100,000 nucleotides. Doesn't sound like much, but since each diploid cell has 6 billion base pairs, there are around 120,000 errors every cell division.

Ribosomal errors during transcription can even change the synthesis of the DNA polymerase proteins, leading to the creation of a mechanism that is already faulty. Since not all ribosomes are created equally, ribosome quality is important. Bacterial mutation rates are greater because bacterial ribosomes are less accurate and produce a lot more errors than human ribosomes. That is a benefit for simple, quickly reproducing life, which is also very vulnerable to the stresses of the molecular chemical environment. Unlike most more complex forms of life, which also have DNA repair mechanisms incorporated into the DNA polymerase, humans have these mechanisms. Some of these processes can often correct mistakes as soon as they are produced, while others can do so over time.

Regarding the pairing of C and T, etc. There are a number of balls in that room that, at first glance, appear to be identical, but if you compare two closely, you could find that one bump is larger or is located incorrectly even if it appears to be same. Proton shift is one such. Here are two instances using the purine guanine (G) and the pyrimidine thymine (T) (G). Please excuse my handwriting; I learned to type at a very young age. Shifted on the right, normal on the left. NA polymerase (as do most more complex forms of life) frequently correct mistakes as soon as they are made and others that correct mistakes later.

Answer: 1.6116

Explanation:

[tex](1.32)(0.82)+(2.94)(0.18)=\boxed{1.6116}[/tex]

The weighted average of a bean in the given sample data is equal to 1.6116 g.

What is the Weighted Average?

The weighted average can be described as a calculation that takes into account the varying degrees of importance of the numbers in a data set. Each number is multiplied by a predetermined weight in the given data set before the final calculation is made in calculating a weighted average.

A weighted average assigns weights that calculate in advance the relative abundance of each data point. A weighted average is commonly determined to equalize the frequency of the values in a data set.

Given the abundance of Black eyes peas, m₁ = 82% = 0.82

The mass of the Black eyes peas, W₁ = 1.32 g

the abundance of cannellini beans, m₂ = 18% 0.18

The mass of cannellini beans, W₂ = 2.94 g

The weighted average = m₁W₁ + m₂W₂ = 1.32× 0.82 + 2.94 ×0.18

The weighted average of a bean = 1.6116 g

Therefore, the weighted average of a bean in the sample is 1.6116 g.

The mass in grams of butane at standard room temperature is 53.21 grams.

How can we determine the mass of an organic substance at room temperature?

The gram of an organic substance at room temperature can be determined by using the ideal gas equation which can be expressed as:

PV = nRT

Pressure = 1.00 atmVolume = 22.4 LRate = 0.0821 atm*L/mol*KTemperature = 25° C = 298 k

60 ml of a 1.0 m solution of h2so4 is mixed with distilled water to make 1 l of solution. what is the molarity

Answers

Answer:

0.057 M

Explanation:

To find the new molarity, you need to (1) find the moles (via the molarity equation using the old molarity and volume) and then (2) calculate the new molarity (via the molarity equation using the combined volume and old moles).

(Step 1)

60 mL / 1,000 = 0.06 L

Molarity (M) = moles / volume (L)

1.0 M = moles / 0.06 L

(1.0 M) x (0.06 L) = moles

0.06 = moles

(Step 2)

0.06 L + 1 L = 1.06 L

Molarity (M) = moles / volume (L)

Molarity = 0.06 moles / 1.06 L

Molarity = 0.057 M

During the distillation nitrogen gas is obtained first, then argon and oxygen. What can u say about the boiling points of these three gases?

Answers

Explanation:

The boiling point of liquid nitrogen, liquid argon, and liquid oxygen are -196°C, -186°C, and -183°C respectively. So, the correct order is nitrogen, argon, oxygen.

Nitrogen:

Since you don't want nitrogen to be condensing everywhere when it gets cold out, elemental nitrogen's boiling point is luckily below zero degrees Celsius. Thank goodness for nitrogen's extremely low boiling point. If it were at zero, boiling water would not produce a lot of heat, necessitating the use of a pressure cooker to prepare foods that typically call for boiling water. Additionally, since the air would be substantially enhanced with oxygen, items may catch fire more quickly (i.e. your home might burst in flame that much more easily). An ugly picture, to be sure.

Argon:

As nonpolar gases, Ar, F2, and Cl2 only display London Dispersion Forces (LDF). These largely negligible forces, which are the product of transient dipoles, must be resisted throughout the boiling process. Since bigger atoms and molecules have valence electrons further from their nucleus, LDF intensity is also directly correlated with atomic or molecular size. Compared to smaller atoms or molecules, these outermost electrons are less attracted to the positive nucleus or nuclei, making it simpler for them to create transient dipoles. As a result, the differing molar masses of each compound—Ar—39.95 g/mol, F—38.00 g/mol, and Cl—70.90 g/mol—can be used to explain the variation in boiling points.

Oxygen:

At 1 atm, oxygen would boil at -183 degrees Celsius if it were a liquid. Although the phase diagram for oxygen is more intricate than this, it is a general phase diagram. Imagine that the term "vaporization" is at the same height as 1 atm, which is roughly halfway up the y-axis. If the y value at that time was equal to 1 atm, the "vaporization" arrow to the right would be directly above -183 degrees Celsius. It's crucial to remember that pressure determines what temperature a substance will boil, melt, condense, or freeze, as you can probably guess. Additionally, the pressure in particular circumstances can affect what phase a material is in.

Answers

The Molar Concentration Of A =0.099 .

The Relative Molar Mass Of A = 35.0129 gm

Given,

Mass of HX = 3.5 g

Moles of solution B ([tex]Na_{2} CO_{3}[/tex]) = 0.05 moles

Volume of HX = 26.10 mL

Volume of Solution B = 25 mL

Molecular weight of solution B = 2(atomic weight of Na )+ atomic weight of C + 3(atomic weight of O)

                 = 2(23) + 12 + 3(16)

                 =106 gm

Equivalent weight of  [tex]Na_{2} CO_{3}[/tex] = molecular weight / 2 = 106 /2  =53 g

Mole = mass / molecular weight

∴0.05 = mass / 106

∴ mass = 5.3 gm [tex]Na_{2} CO_{3}[/tex]

Normality = mass ÷ (equivalent weight × volume of the solution in liter)

                = 5.3 ÷( 53 × 0.025)

                =4 N

So, by using formula ,

[tex]N_{1} V_{1} =N_{2} V_{2}[/tex]

[tex]N_{1}[/tex] = normality of solution B = 4 N

[tex]V_{1}[/tex] = volume of solution B = 25 mL

[tex]N_{2}[/tex] = normality of solution A = ? N

[tex]V_{2}[/tex] =Volume of solution A = 26.1 mL

∴ 4×25 = [tex]N_{2}[/tex] × 26.1

∴[tex]N_{2}[/tex] = 3.83 N

∴ normality of solution A = 3.83 N

from Formula of the normality we can find the equivalent weight of the A

Normality = mass of HX ÷ (equivalent weight × volume of the solution in liter)

3.83 = 3.5 ÷( equivalent weight × 0.0261)

equivalent weight = 35.0129 g

In case of HX the electron transfer is 1 ,so equivalent weight = molecular weight ; which is also termed as relative molar mass in given case.

∴The Relative Molar Mass Of A = 35.0129 g

Molar concentration = mass / molar mass

                               = 3.5 / 35.0129

                               = 0.099 mole

Gently use your finger to touch the surface of the water and observe what happens.Data and observations: ObservationsBlack pepper in water Touching water without soap Touching water with soap Phenomena Reflective Question: How does the surface tension of water allow for it to interact with Earth materials?Activity Three: Investigating Solubility A liquid is polar, which means a substance can easily dissolve in it. How can you test waters polarity compared to other substances? To measure solubility, it is necessary to compare initial and final results using your visual observations.Describe the plan you will follow to determine this:Record your data and observations: Add food coloring to each liquid. Observe each reaction and record your observations in the table below. Time Water Vegetable Oil0 seconds 5 seconds 10 seconds 15 seconds 20 seconds Phenomena Reflective Question: Explain why water is called a universal solvent. How does this polarity allow for water to interact with Earth materials?Activity Four: Investigating Specific Heat CapacitySpecific heat is the amount of heat energy needed to change the temperature of 1 gram of the substance one degree Celsius. Some objects' specific heat allows them to heat up or cool down faster than others of equal mass. How can you compare waters specific heat to other substances? How does the specific heat of water affect how other objects, such as a damp cloth, warm up or cool down? To measure specific heat, it is necessary to compare initial and final results.Describe the plan you will follow to determine this:Record your data and observations: Observe the temperature of the damp sponge/cloth after being placed under a heat source. Caution: do not set the damp sponge or cloth to close to the heat source. Record your observations. Time Damp Sponge/Cloth0 seconds 5 seconds 10 seconds 15 seconds 20 seconds Phenomena Reflective Question: How does waters specific heat capacity come into play when it interacts with Earth materials or affect surface processes?Activity Five: Investigating Expansion and DensityDensity of an object can be found by calculating mass divided by volume. If two objects have the same mass, but one has a greater volume, the object with more volume is less dense. Does waters density change when it is frozen? Describe the plan you will follow to determine this:Record your data and observations:Phenomenon Reflective Question: Did the density of water change when it changed from solid to liquid? How do you think the density of water has an effect on Earth materials and surface processes?Evaluating the Design:Part of an investigation is to evaluation how well your investigation gave you the data you needed. In this report, include the following:1. an evaluation of the plan you made for the various activities and how the data was collected2. a description of how well the data allowed you to infer the effect of water on materials and processes in the world3. a description of how to further investigate the effects of water and collect more accurate and precise data Which choice most effectiveely sets up the information that followa? b. Being cleaned and restored c. At risk of destruction A group of people were given a personality test to determine if they were Type A or Type B. The results are shown in the table below: Male Female Type A 65 85 Type B 38 12 Compare P(Male or Type B) with P(Male | Type B). P(Male or Type B) > P(Male | Type B) P(Male or Type B) = P(Male | Type B) P(Male or Type B) < P(Male | Type B) There is not enough information. In what way can computers allow artist to make prints?
