Answer 1

5.Mitos is a type of cell division occurs in somatic cells. During mitosis the diploid parent cell is divided into two diploid daughter cells. As a result of this daughter cells have a same number of chromosome as parent cell. So the correct answer is the same number of chromosome as the parents.

6. DNA replication takes place in the S - phase (synthesis phase) of the cell cycle. The synthesised DNA is divided into daughter cells with the help of mitotic cell division. So the correct answer is none of the above.
