Best Answer

DNA is copied (or replicated) by an enzyme called DNA polymerase. This enzyme generally operates in the 3' to 5' direction. However, this enzyme also has a 5' to 3' exonuclease activity, which enables it to remove certain wrong bases and insert correct ones. This ensure that the DNA is copied correctly

DNA is copied in which stage of the cell cycle?

DNA is replicated during the Synthesis (S) phase of cell growth. This comes after G1 and before G2. Mitosis follows G2.

Stage in cell cycle when DNA is copied?

The stage in the cell cycle when DNA is copied is the S phase of the interphase. It refers to the resting phase between successive mitotic divisions of a cell.

In what stage of the cell cycle is a cells DNA copied?

Synthesis (S) Phase:"A Cell's DNA is copied during this phase. At the end of this phase, each chromosome consists of two chromatids attached at the centromere."(C) BIOLOGY Johnson Raven (Honors)
