Question

Match each phase of interphase to the cellular activities performed during each.

A) G1 phase / DNA synthesis
B) S phase / Cell growth
C) G2 phase / Preparation for cell division
D) M phase / Mitosis

Answer 1

The process of cell division involves interphase, which is comprised of the G1 phase for growth and preparation for DNA replication, the S phase where DNA is replicated, and the G2 phase which involves further growth and preparation for division. The mitotic phase follows interphase.

Step-by-step explanation:

Stages of Interphase and Cellular Activities

The process of cell division is a complex mechanism involving different stages of growth and DNA replication. Each phase of interphase correlates with specific cellular activities:

1. G1 Phase: This phase, also known as the first gap, is when a cell experiences growth and prepares for DNA replication. It accumulates building blocks of DNA and proteins, and energy reserves.
2. S Phase: During the synthesis phase, the cell performs DNA replication, ensuring that each daughter cell will have an identical set of genetic material post-division.
3. G2 Phase: In this second gap phase, the cell continues to grow and produces proteins and organelles that are required for cell division.

Following interphase, the cell enters the M phase (mitotic phase) where mitosis (nuclear division) and cytokinesis (division of the cytoplasm) occur to form two daughter cells.
