Question

A cell has 32 chromosomes. It undergoes mitotic division. What will be the chromosome number (N) during metaphase? What would be the DNA content (C) during anaphase?

Answer 1

The number of chromosomes does not change during metaphase or anaphase. So, the number will remain 32. We know that DNA replication takes place during S phase and hence, the DNA content becomes double just after the S phase; and will remain so during mitosis until the completion of Anaphase.
