Write 5 sentences OR a list of numbered steps to explain the process of DNA replication. You’ll also complete sketch notes to supplement your written understanding.
Your writing must incorporate the following components
Direction DNA is synthesized
Description of how DNA replication is considered semiconservative
Role and location of helicase
Role and location of topoisomerase
Role and location of RNA primers
Role and location of DNA polymerase
Distinguishing between leading/lagging strand and identifying which strand replicates continuously and which replicated discontinuously
Okazaki fragments
Role and location of ligase
This results in the formation of small fragments known as Okazaki fragments. The role of the ligase is to seal the gaps between the Okazaki fragments and join them to form a continuous strand.
Here are the five sentences to explain the process of DNA replication:The process of DNA replication involves the synthesis of new DNA strands by copying the existing DNA strands.This process is considered semi-conservative since each daughter DNA molecule is composed of one parent strand and one newly synthesized strand.
During DNA replication, the enzyme helicase is responsible for unwinding the double helix by breaking hydrogen bonds between the base pairs.The enzyme topoisomerase relieves the tension that arises ahead of the replication fork.
DNA polymerase is the enzyme responsible for adding nucleotides to the growing DNA strand. It can only add nucleotides to the 3’ end of the strand.There are two strands in DNA:
the leading strand and the lagging strand. The leading strand replicates continuously, while the lagging strand replicates discontinuously. The RNA primers are located on the lagging strand and are responsible for providing a free 3’ OH group for DNA polymerase to add nucleotides.

The shaded individuals in the pedigree diagram below are color-blind. The
only unknown is whether the mother in the first generation has normal color
vision.
What is true about the mother?
A. She must have normal color vision.
B. She must be color-blind.
C. She could be homozygous for normal color vision.
D. She could be heterozygous for color blindness.
The correct answer is D. She could be heterozygous for color blindness.
What is Color Blindness?
Color blindness is a condition in which a person's ability to perceive colors is impaired. Most cases of color blindness are genetic and are caused by a defect or absence of the color-sensitive pigment in the cones of the retina. This defect or absence can affect one or more of the three types of cones that are responsible for detecting red, green, and blue light.
In the pedigree diagram, the shaded individuals are color-blind, which is a recessive X-linked trait. This means that the individuals in the pedigree who are shaded must have inherited a color-blindness allele from both of their parents, and that the mother of the first generation could be either homozygous for normal color vision (XX) or heterozygous for color blindness (XbX).
If the mother in the first generation had normal color vision, she would have to be homozygous for normal color vision (XX), and all of her sons would also have normal color vision because they would inherit a normal X chromosome from her. However, this would mean that none of her daughters would be color-blind, and there are shaded females in the pedigree. Therefore, it is not possible for the mother to have normal color vision.
If the mother in the first generation is heterozygous for color blindness (XbX), she would have a 50% chance of passing on the color-blindness allele to each of her children. This means that all of her sons would have a 50% chance of being color-blind, as shown in the pedigree, and that her daughters would have a 50% chance of inheriting one copy of the color-blindness allele and being carriers, but they would not be color-blind themselves. This is consistent with the shaded females in the pedigree who are carriers of the color-blindness allele.

14. While working with a particular strain of E. coli, you discover that it transcribes the lac genes at a high level when no lactose is present in the cell's medium.
a) Explain how the lac operon functions typically.
b) List the possible causes of this abnormal activity.
c) Then design an experiment to determine which of these possible causes is the case with your bacterial colony.
The lac operon follows a negative, inducible mode of regulation. This means that the transcription of the operon is turned OFF in the absence of lactose and is only induced into activity when lactose is present in the medium.
What is lac operon?
a) If the genotype of the lac operon is normal, i.e. it does not contain any mutations, then,If lactose is present in the medium:-When lactose is present in the medium, it is translocated into the cell because the operon always produces a small amount of permease. The allolactose molecule binds to the repressor molecule and inactivates it.An inactivated repressor can no longer bind to the operator and as a result all genes are transcribed, i.e. the operon is turned on.Also, the absence of glucose leads to the production of large amounts of cAMP in the cell, which binds to the CAP protein. This complex then binds to the CAP site and increases the rate of transcription of the operon.If lactose is not present in the medium:-In the absence of lactose, the repressor remains active and binds to the operator. This prevents RNA polymerase from binding to the promoter and the operon is not transcribed, i.e. the operon is turned off.When both lactose and glucose are present:-Glucose will be used first because it is the preferred energy source and during this time there will be minimal transcription of the lac operon.b) If the lac operon is expressed at high levels even in the absence of lactose, it means that it shows constitutive expression, i.e. it is expressed regardless of the availability of lactose in the medium.This can be possible for two reasons:-1) A mutated lacI gene (lacI-) that produces an inactive or mutant repressorIn this case, the mutation alters or alters the promoter region of the lac1 gene, since this gene has a promoter separate from that of the structural genes. This means that if the promoter of that gene is altered so that it can no longer bind to the RNA polymerase enzyme, that gene will not be transcribed or expressed. As a result, the repressor protein will not be produced and the operon will therefore be constitutively active.2) Mutation operator, i.e. operator Oc In this mutation, the repressor binding site on the operator is mutated in such a way that it cannot bind to the repressor protein even in the absence of lactose. If the repressor cannot bind to the operator, then the operon will be expressed regardless of the presence or absence of lactose.C)In the case of a mutant lacI gene, we know that the promoter of this gene will be changed so that it can no longer bind to the RNA polymerase enzyme and the gene will not be transcribed. that is, this gene will not produce any mRNA or repressor protein in the absence of lactose, whereas the normal operon does,In the case of a constitutive operator, the operator will not be able to bind the repressor even in the absence of lactose. Thus, even if lactose is not available in the medium, there will be a higher concentration of free repressor protein in the cytoplasm of the cell.This means that in the case of the lacI- mutant there will be no repressor protein, while in the case of the Oc mutant there will be a high concentration of the repressor protein in the cell cytoplasm.Thus, this difference in the presence of the repressor protein can be used to distinguish between a cell with a normal and a lacI-mutated operon by Western Blot analysis.This is because this technique tests for the presence of specific proteins present in the cell sample using complementary antibodies that specifically bind to the target protein and are conjugated to a marker enzyme that stains the chromogenic substrate blue.To know more about lac operon, click the link given below:

The evolution of cuticles presented land plants with the challenge of preventing water loss from leaves and preventing the entry of CO2 required for photosynthesis, while stomata allow CO2 to diffuse and can close to prevent water loss.
1. Cuticle prevents water loss from leaves and prevents entry of CO2 required for photosynthesis.
2. Stomata allow CO2 to diffuse and can close to prevent water loss.
The waxy cuticle on the surface of leaves helps prevent water loss, but it also creates a barrier that prevents gases from entering and leaving the plant. This presents a problem for photosynthesis, which requires the uptake of carbon dioxide (CO2) and the release of oxygen (O2).
Stomata, have tiny pores on the leaf surface, allowing CO2 to diffuse into the leaf and O2 to diffuse out. Additionally, they can close to prevent excessive water loss through transpiration. The evolution of stomata allowed plants to thrive on land by overcoming the challenge of gas exchange while minimizing water loss.

The 5' end of mRNA serves as a binding site for __________, which allow translation to begin.
a.The promotor proteins
b.The ‘A’ site of the large ribosomal subunit
c.tRNA
d.Initiation factors
Each mRNA molecule being translated often undergoes numerous initiations. The 5′ end of the mRNA is threaded into a new ribosome as soon as the previous ribosome has translated enough of the nucleotide sequence to move out of the way. Hence, it allows the translation to begin.
A ribosome outside the nucleus decodes messenger RNA (mRNA) during translation to produce a specific polypeptide or amino acid chain. The polypeptide performs its unique functions inside the cell after folding into a functional protein. The ribosome facilitates decoding by promoting the binding of complementary tRNA anticodon sequences to mRNA codons. The tRNAs transport certain amino acids that are linked together to form a polypeptide as the mRNA passes through and is "read" by the ribosome.
