What happens during the first step in DNA replication?

Biology
2 answers:
Nina [5.8K]3 years ago
7 0

The first step in DNA replication is the separation of the two DNA strands that make up the helix that is to be copied.

It starts when a protein starts the unwinding of the DNA helix. Next comes the separation of the DNA strands right before the transfer of genetic data to the newly assembled DNA strands starts. A protein known as helicase is what breaks down the hydrogen bonds between strands of DNA during replication.

Muscles that move the eyeball have ________ fibers.
ozzi

Muscles which are responsible for the movement of the eyeball have fast fibers. Thus, the correct option is A.

<h3>What are fast muscle fibers?</h3>

Fast-twitch muscle fibers are the muscle fibers which provide bigger and more powerful forces, however for shorter durations and fatigue quickly. They are more anaerobic with less blood supply, and hence are sometimes also referred to as white fibers or type II fibers.

Fast-twitch muscle fibers are activated by the high intensity movements which are sustained in short bursts. Examples of movements include sprints, burpees, and quick lateral movements.

Therefore, the correct option is A.
