Question

Which statement BEST describes what happens during the S-phase of the cell cycle?

A.Protein synthesis needed for spindle formation and mitosis.

B.DNA replication where the amount of genetic material is doubled.

C.The cell partitions the two copies of genetic material into the two daughter cells.

D.Cell division occurs and two cells are left; thus the cell cycle begins again.

Answer 1

Answer:

B

Explanation:

The S phase of a cell cycle occurs during interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA. In this way, the genetic material of a cell is doubled before it enters mitosis or meiosis, allowing there to be enough DNA to be split into daughter cells.
