<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.
Answer: They represent different concepts
Scientists most often produce new genetic variations of organisms by causing mutations with radiation or chemicals and then selectively breeding in order to emphasize the desired traits in the new variations. The Dachshund is an example of this. By breeding two dogs with a similar mutation that caused student legs and elongated backs breeders were able to create a new variation not found in nature.
Answer:
Prophase
The replicated chromosomes thicken and become visible as separate chromosomes during prophase stage of mitosis. :)
