WebThe 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. WebOne chromosome has 2 strands of DNA in a double helix. But the 2 DNA strands in chromosomes are very, very long. One strand of DNA can be very short - much shorter than even a small chromosome. Strands of DNA are made by joining together the 4 DNA bases in strings. The 4bases are A, C, G, and T.
