If the new gene "works", then it will synthesize a missing enzyme or structural protein. A gene is a protein-coding nucleotide (DNA) sequence.
A gene is a fragment of DNA that is used by the cell to create a complementary mRNA sequence by a process called transcription.
Subsequently, this mRNA is then used to synthesize a protein by a process called translation.
When a gene is defective, a change in the nucleotide sequence (i.e., a mutation) can restore normal gene function and thus produce a functional protein.

glucose molecules are to starch as ________ are to proteins.
Answer:
Amino acids
Explanation:
Glucose molecules are to starch what amino acids are to proteins; the glucose molecules are the monomeric units of the starch, just as the amino acids are the monomeric units of the protein.
What is the significance of the monomers?Polymers such as starch, protein, and fatty acids are found in living bodies such as those of animals and plants and polymers are made up of monomeric units such as glucose monomers that are bonded to each other by glycosidic bonds make starch, and amino acids are the monomeric units of proteins that are bonded by peptide bonds. These are necessary for the storage molecule, as well as for the cell's structural and functional units.
Hence, glucose molecules are to starch what amino acids are to proteins; the glucose molecules are the monomeric units of the starch, just as the amino acids are the monomeric units of the protein.

what is the proton gradient in cellular respiration?
Answer:
The proton gradient produced by proton pumping during the electron transport chain is used to synthesize ATP. Protons flow down their concentration gradient into the matrix through the membrane protein ATP synthase, causing it to spin (like a water wheel) and catalyze conversion of ADP to ATP.
A proton gradient is a difference in the concentration of protons (H+) across a membrane. In cellular respiration, a proton gradient is created by the electron transport chain (ETC) in the mitochondria.
The ETC is a series of proteins that shuttle electrons from NADH and FADH2 to oxygen. As the electrons are shuttled, they lose energy, which is used to pump protons out of the mitochondrial matrix into the intermembrane space.
This creates a concentration gradient, with more protons in the intermembrane space than in the mitochondrial matrix.
The proton gradient is used to power ATP synthesis. The enzyme ATP synthase, which is located in the inner mitochondrial membrane, uses the energy of the proton gradient to drive the synthesis of ATP from ADP and inorganic phosphate (Pi).
The proton gradient is a key part of cellular respiration, and it is essential for the production of ATP. Without the proton gradient, ATP synthesis would not be possible, and cells would not be able to produce the energy they need to function.

How was Earths climate changed over time?
Answer:
Explanation:
These changes have been triggered by the changing configuration of continents and oceans, changes in the Sun's intensity, variations in the orbit of Earth, and volcanic eruptions.
Which equation can be used to solve for acceleration?
Answer:
To do this you need to know equation for acceleration: a = Δv / Δt where a is acceleration, Δv is the change in velocity, and Δt is the amount of time it took for that change to occur. The unit for acceleration is meters per second per second or m/s2.

4. Arrange Write the following steps in the order in which they occur during glycolysis
A six-carbon molecule is broken down into two three-carbon molecules.
Two NADP molecules are converted into two NADH molecules.
Two phosphate groups from two ATP molecules are joined to glucose.
Two three-carbon molecules are converted into two Folecules of pyruvate as four
molecules of ATP are produced.
The correct order of glycolysis reactions is:
Two phosphate groups from two ATP molecules are joined to glucose.Two NADP molecules are converted into two NADH molecules.A six-carbon molecule is broken down into two three-carbon molecules.Two three-carbon molecules are converted into two molecules of pyruvate as four molecules of ATP are produced.During glycolysis, the glucose molecule is converted to Glucose-6-phosphate as a result of phosphorylation. The phosphate group from ATP is joined to the glucose molecule by an enzyme known as hexokinase.
The glucose-6-phosphate then undergoes isomerization to become fructose-6-phosphate which is then phosphorylated again by the hexokinase enzyme to become fructose-1,6-biphosphate.
An aldolase enzyme converts fructose-1,6-biphosphate to one molecule of glyceraldehyde-3-phosphate and one molecule of dihydroxyacetone phosphate. The latter is then converted to another molecule of glyceraldehyde-3-phosphate.
A dehydrogenase enzyme converts glyceraldehyde-3-phosphate to 1,3-bisphosphoglycerate with NADH being generated from the reduction of NAD+.
A kinase enzyme then converts 1,3-bisphosphoglycerate to 3-phosphoglycerate with ATP being generated from ADP. A mutase enzyme quickly converts the 3-phosphoglycerate to 2-phosphoglycerate while an enolase enzyme converts the latter to phosphoenolpyruvate.
Finally, a pyruvate kinase enzyme converts phosphoenolpyruvate to pyruvate with another ATP being generated.

dna is a double-stranded molecule made up of complementary, antiparallel strands. based on what you know about complementary base pairing, fill in the rest of the details in the figure.
The details in the figure correspond to the elements that the DNA strands have in their ends. Also, they correspond to the antiparallel strand with the complementary bases.
The DNA has two antiparallel strands with complementary bases (thymine, adenine, guanine, and cytosine). That is to say, that T pairs with A and G with C. Also, they have specific elements in their ends.
The 3' strand in its end has a hydroxyl (OH) group.The 5' strand in its end has a phosphate group.There is a complementary strand with its respective nucleotides that will pair with the other strand according to their specific bases (A-T; C-G)
In conclusion, the top left end of the 3' strand has a hydroxyl group, while the top right, the 5', has a phosphate group. The complementary strand will go the other way round, from 5' to 3', so the hydroxyl and phosphate groups would be on the right and the left, respectively. The bottom strand is the complementary one, and it runs from 3' to 5'.
