a biologist measures the amount of dna in cells growing in a laboratory. she should find that the amount of dna doubles.
a during s phase.
b at the end of g2 phase.
c right after cytokinesis.
d during mitosis.
e in the middle of g1 phase.

Explanation:

DNA replication occurs during the S - phase of the cell cycle, which results in the doubling of the amount of DNA. In G1 phase, the cell grows and prepares for DNA synthesis. In G2 phase, the cell prepares for mitosis. Mitosis is the process of nuclear division and cytokinesis is the division of the cytoplasm.

Answer:

A. during S phase.
