Question

scientists isolate cells from an individual in various phases of the cell cycle. they find a group of cells that have 1½ times more dna than do g1 phase cells. the cells of this group are ____. in the s phase of the cell cycle between the g1 and s phases in the cell cycle in the g2 phase of the cell cycle in the m phase of the cell cycle

Explanation:

In the cell cycle, DNA replication occurs in the S - phase. G1 phase cells have a certain amount of DNA. Cells in S - phase are in the process of replicating DNA, so they have an intermediate amount of DNA between G1 and G2. Since the described cells have 1½ times more DNA than G1 phase cells, they are actively replicating DNA and are in the S - phase.

Answer:

In the S phase of the cell cycle
