True or False:
Binary fission, mitosis, and meiosis all require DNA replication before division can occur.
Correct Answer
True
Explanation
True. All three division processes begin with DNA replication:
- Binary fission - the single prokaryotic circular chromosome is duplicated first
- Mitosis - DNA replication occurs during interphase (S phase) before mitosis begins
- Meiosis - likewise, DNA replication during interphase produces the duplicated chromosomes needed for both meiotic divisions
Without DNA replication, each daughter cell would receive only half the genetic material needed.
