Scientists isolate cells in various phases of the cell cycle. They find a group of cells that have times more dna than g1 phase
ratelena [41]

Answer:

in the S phase of the cell cycle

Explanation:

<em>Scientists isolate cells in various phases of the cell cycle. They find a group of cells that have 1.5 times more DNA than G1 phase cells. The cells of this group are _____.</em>

The cell cycle has two main stages which is the interphase and the M phase.

While the M phase is characterized by active division, the interphase consists of G0 phase which is entirely a resting phase for cells that do not need to divide ordinarily, G1 phase which is a phase for cell drowth and development, S phase which is a phase for DNA synthesis or replication and G2 phase which is a phase for protein synthesis.

Hence, cells in the S phase and G2 phase of the cell cycle are expected to have more DNA than cells in the G0 and G1 phase.

<em>Essentially, the amount of DNA is doubled in the S phase. Therefore, if the cell group have 1.5 times more DNA than G1 phase cells, it means the cells are still in S phase.</em>
