Question

What would be the DNA content of the cell at G1, G2, anaphase stage, when the content after the mitotic phase is 40pg

• A. G1=40 pg, G2=80 pg, anaphase= 40 pg
• B. G1=40 pg, G2=80 pg, anaphase= 80 pg
• C. G1=80 pg, G2=40 pg, anaphase= 40 pg
• D. G1=80 pg, G2=40 pg, anaphase= 80 pg

Answer 1

The correct option is B G1=40 pg, G2=80 pg, anaphase= 80 pg

1. In G${}_1$ phase the amount of DNA is the same as 40 because the cell is metabolically active but no division of DNA is observed.
   
2. In G${}_2$ phase the DNA gets doubled as it has gone through the synthesis phase which is characterized by the replication of DNA.
3. In mitosis since equational division occurs the DNA content remain 4C through the process before the transfer of DNA into daughter cells.

So the correct option is "G${}_1$=40 pg,G${}_2$=80 pg,anaphase=80pg"
