What is occurring in the G1 and G2 phases of a normal cell cycle?
a
chromosome replication
b
cell division
c
growth
d
nuclear division
The correct answers are:
a) Chromosome replication occurs in the G1 phase of the cell cycle. During this phase, the cell grows and prepares for DNA replication.
d) Nuclear division occurs in the G2 phase of the cell cycle. This phase follows DNA replication and is characterized by further cell growth and preparation for cell division.
