Q. Pick out the correct statements. I.Mitosis takes place in the somatic cells and meiosis takes place in the germ cells II.During mitosis, the DNA replicates once for one cell division and in meiosis the DNA replicates twice for two cell divisions. III.Mitosis and meiosis occur both in sexually and asexually reproducing organisms.
A) I only
B) II only
C) III only
D) I and II only
Explanation
During mitosis, DNA replicates once for one cell division and in meiosis also the DNA replicates once for two cell divisions so, the chromosome number becomes half in meiosis. Mitosis occurs in both sexually and asexually reproducing organisms, while meiosis occurs only in sexually reproducing organisms.
