Can there be mitosis without DNA replication in S phase? | NCERT solution | Class 11 Biology | Unit-10 Cell Cycle and Cell Division



Q.14:- Can there be mitosis without DNA replication in S phase?

 

Answer:-



No, there cannot be mitosis without DNA replication in S phase because additional DNAs are required for the formation of new cells. DNA duplication is important as it maintains the chromosome number in the daughter cells and hence Mitosis is an equational division. Therefore, the duplication of DNA is an essential step and without it, no mitosis can take place.
