Humans produce skin cells by mitosis and gametes by meiosis. the nuclei of skin cells produced by mitosis will have
a) half as much dna as the nuclei of gametes produced by meiosis.
b) the same amount of dna as the nuclei of gametes produced by meiosis.
c) twice as much dna as the nuclei of gametes produced by meiosis.
d) four times as much dna as the nuclei of gametes produced by meiosis.

C) twice as much DNA as the nuclei of gametes produced by meiosis.

Explanation:

The somatic cells are diploid cells, which means, carries two copies of each chromosome. Gametes (eggs and sperm) are haploid cells, which means they only carry one copy of each chromosome, it means, they posses half the genetic information of any somatic cell, like skin cells.

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
