<u>Answer:</u>
A is a DNA sequence that binds regulatory proteins that interact with promoter-bound proteins to activate transcription.
<u>Explanation:</u>
Background Knowledge:
DNA contains genes which is a particular segment of DNA. A gene usually has regulatory regions and a structural region.
Promoter: The regulatory region located to the 5 prime end of coding strand of the gene which is called as promoter that controls the binding RNA Polymerase during transcription.
The Terminator is the other regulatory region, located to the 3 prime end of coding strand of the gene. The terminator region causes RNA polymerase to stop transcription.
Structural region is the region present between the promoter and terminator.
Answer of the question is:
A is a DNA sequence that binds regulatory proteins that interact with promoter-bound proteins to activate transcription.
Is it just me or is there nothing there?
If a cell’s nucleus has 55% adenine bases it also has 55% thymine bases, so the percentage of cytosine bases is 45% as same as guanine bases.
This is known as Chargaff's rule which states that DNA should have a 1:1 ratio of pyrimidine and purine bases (the amount of guanine should be equal to cytosine and the same thing with adenine and thymine).
DNA molecule globally has percentage base pair equality: %A = %T and %G = %C.
