Q. The number of DNA strands in chromosome at G2-stage of cell cycle is

Cell Cycle and Cell Division

Solution:

The number of DNA strands in the chromosome at the G2 stage of the cell cycle is four due to replication of DNA during the S-phase. There are 2 strands of DNA at the start of cell division. And after replication, each strand synthesizes a new strand, giving rise to a total of 4 strands.
