DNA duplication occurs in
DNA duplication occurs in
Open in App
Solution
The correct option is C Meiosis I and mitosis
- DNA duplication os required so that the genetic material in the cell is doubled and can be equally distributed between the 2 daughter cells.
- On mitosis the DNA is duplicated during the S phase of the interphase after which the cell enters the cell division and the genetic material is distributed between the daughter cells equally.
- In meiosis the cells undergoes meiosis 1 and meiosis 2 where the genetic material is already duplicated in the S phase of the interphase before entering the cell division after the first meiosis the genetic material is halved of the mother cell. After this the cell enters the meiosis 2 where the stages are almost as same as the mitosis where the genetic material is distributed between the cells during the anaphase.
- Therefore the answer option 'Meiosis I and mitosis' is correct.
