Question
Can there be mitosis without DNA replication in S phase?
Solution
- Mitotic cell division cannot take place without DNA replication in S phase.
- Two important events take place during the S phase: one is the synthesis or duplication of DNA and the other is the duplication of the centriole.
- DNA duplication is important as it maintains the chromosome number in the daughter cells.
- Mitosis is an equational division. Therefore, the duplication of DNA is an important step
