Question

If DNA content after M phase is 2C then DNA content after G2 G1 S are?

Answer 1

G1 phase is the interval phase between mitosis and initiation of DNA replication. The initial amount of DNA is denoted as 2C ( C, is the haploid DNA content) which is then increases to 4C at the completion of S-phase. However there is no increase in the chromosome number; if the cell had diploid or 2n number of chromosomes at G1, even after S-pahse the number of chromosomes remains the same that is 2n. So if content after M-phase is 2C it will remain as 2C only.

if you are satisfy with my ans then mark me as a brainlist

if there is something wrong then kindly rectify it

Answer 2

the DNA content is2C after G2 G1 and S phase
