The answer to the question is letter A. perihelion.
>The perihelion<span> is the point in the </span>orbit<span> of a </span>planet<span>,or a body</span><span> where it is nearest to its point of orbit, generally a star. It's the opposite of </span>aphelion<span>-- the point in the orbit where the celestial body is farthest from its point of orbit.
>></span>The perihelion and aphelion are the nearest and farthest points <span>of a body's direct </span>orbit<span> around the </span>Sun<span>.</span>
Answer:
False.

Answer:
CHK2, p53, p21, cell cycle progression.
Explanation:
In a normal cell with no LFS mutation, during the G1 stage of cell cycle progression, the CHK2 activates if there is damage in the DNA. CHK2 activates p53, which is a tumor suppressor protein that will hold the cell cycle in G1/S until the DNA is repaired. The p53 protein activates p21, a protein that binds to CDK2 and stops the cell cycle. The cell cycle will continue once the damage is repaired.
Answer:
Thus, the major difference between DNA and RNA is that DNA is double-stranded and RNA is single-stranded. DNA is responsible for genetic information transmission, whereas RNA transmits genetic codes that are necessary for protein creation.
