Biology
1 answer:
Taya2010 [7]2 years ago
4 0

Answer/Explanation:

First, initiator protein unwinds a short stretch of the DNA double helix. <u>The length of the DNA double helix about to be copied must be unwound. </u> In addition, the two strands must be separated, much like the two sides of a zipper, by breaking the weak hydrogen bonds that link the paired bases.   Once the DNA strands have been unwound, they must be held apart to expose the bases so that new nucleotide partners can hydrogen-bond to them. Then, a protein known as helicase attaches to and breaks apart the hydrogen bonds between the bases on the DNA strands, thereby pulling apart the two strands.

Which hair cell type is primarily responsible for electromotile (movement) activity that is considered a form of amplification?
Morgarella [4.7K]

Answer: Outer hair cell

Explanation:

The hair cell is located in the brain and its responsible for amplification of sound. The hair cell length changes in response to stimulus. For amplification a low input is needed and the surrounding frequency must be close to basila membrane located in the inner hair cell. They can amplify low sound using their hair bubbles. The outer hair cell increase hearing sensitivity and a damage to it brings about low sensitivity.

Also, outer hair cell do not regenerate itself and a damage to it means a permanent damage.
