Question

Can the nucleus and nucleolus be seen during interphase?

A) Yes, both are visible
B) No, neither is visible
C) Yes, the nucleus is visible, but the nucleolus is not
D) No, the nucleus is visible, but the nucleolus is not

Answer 1

During interphase, the nucleus can still be seen, but the nucleolus is not visible.

Step-by-step explanation:

During interphase, the nucleus can still be seen, but the nucleolus is not visible.

Interphase is the longest phase of the cell cycle and is divided into three stages: G1, S, and G2. In the G1 stage, cells grow and carry out normal metabolic activities. The S stage is when DNA replication occurs, resulting in the formation of identical pairs of DNA molecules called sister chromatids. The G2 stage is a preparation phase for cell division. Throughout interphase, the nuclear DNA remains in a semi-condensed chromatin configuration that can be visualized under a microscope, but the nucleolus, which is responsible for manufacturing RNA, is not visible.
