Answer
The cell checks the accuracy of its DNA replication and repairs any errors during the Second gap (G2) phase.
Solution
a
First gap (G1) phase: This phase is primarily focused on cell growth and preparation for DNA replication
b
Mitosis: This is the phase where the cell divides its chromosomes into two daughter cells. It does not involve checking DNA replication accuracy
c
Synthesis (S) phase: This phase is where DNA replication occurs, but the primary checking and repair of DNA errors happen later
d
Meiosis: This is a type of cell division that reduces the chromosome number by half, not directly involved in checking DNA replication accuracy
e
Second gap (G2) phase: This phase involves the cell checking the accuracy of DNA replication and repairing any errors detected before proceeding to mitosis
Key Concept
G2 phase
Explanation
The G2 phase is crucial for ensuring that the cell's DNA is accurately replicated and any errors are repaired before the cell enters mitosis. This ensures the integrity of the genetic material passed on to daughter cells.
