Question

For each phase of the cell cycle for a normal human cell, identify if the cell possesses a 2n amount of DNA, a 4n amount of DNA, or an amount somewhere between 2n and 4n.

A) True
B) False

Answer 1

In the cell cycle of a normal human cell, the DNA amount varies between 2n and 4n at different phases.

Step-by-step explanation:

The cell cycle of a normal human cell consists of several phases: G1, S, G2, and M. During the G1 phase, the cell grows and prepares for DNA replication. At the beginning of the S phase, DNA replication occurs, resulting in the cell possessing a 2n amount of DNA. In the G2 phase, the cell continues to grow and makes preparations for mitosis. Finally, during the M phase (mitosis), the cell divides, and each daughter cell possesses an amount of DNA between 2n and 4n, depending on the stage of mitosis.
