Question

in which stage of cell cycle each choromosome is duplicated and so it consists of two chromatids
GI phase
S phase
M phase
G2 phase​

Answer 1

Answer:

In the S phase (synthesis phase), DNA replication results in the formation of two identical copies of each chromosome—sister chromatids—that are firmly attached at the centromere region. At this stage, each chromosome is made of two sister chromatids and is a duplicated chromosome.
