Answer:

<h2>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).</h2><h2>Meiosis 1 is reductional division and meiosis 2 in equational division.</h2><h2>after meiosis the number of chromosome  and DNA become half.</h2>

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.
