what will be the DNA content of the cell at G1 , after S and G2. if the content after M phase is 2C ????

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.
