Question

Scientists isolate cells in various phases of the cell cycle. They find a group of cells that have times more dna than g1 phase cells. The cells of this group are _____.

Answer 1

Answer:

in the S phase of the cell cycle

Explanation:

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 _____.

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.

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.
