1. If the amount of DNA in a somatic cell equals C during G1 of interphase, how much DNA is present in the cell during each phase of mitosis and meiosis?

Respuesta :

Answer:

In mitosis, the DNA replication occurs in S phase , so the amount of DNA increases in S phase and remain double until cell division( karyiokinesis).

Meiosis 1 is reductional division and meiosis 2 in equational division.

after meiosis the number of chromosome  and DNA become half.

Explanation:

Mitosis: interphase ( G1, S,and G2) and mitotic phase ( prophase, metaphse, anaphase ,telophase)

c= chromose number ,N = DNA  amount

In mitosis, the chromosome number remains same until anaphase, so the number of chromosome become doubles in anaphase and telophase.

In mitosis, the DNA replication occurs in S phase , so the amount of DNA increases in S phase and remain double until cell division( karyiokinesis).

meiosis  ; Meiosis 1 and Meiosis 2,

Meiosis 1 is reductional division and meiosis 2 in equational division.

after meiosis the number of chromosome  and DNA become half.
