Question

In the process of meiosis, there are two sequential cycles of nuclear and cell division. How many cycles of DNA replication are required in meiosis ?

Answer 1

Answer:

One

Explanation:

DNA replicates during the S phase of meiosis. During meiosis the cell passes only once through this phase and DNA synthesis by replication occurs only once during this phase. Hence, only one cycle of DNA replication occurs during meiosis.So, the correct option is 'one. ( toppr.com)

Answer 2

In most plants and all animal species, it is typically diploid cells that undergo mitosis to form new diploid cells. In contrast, meiosis consists of two nuclear divisions resulting in four nuclei that are usually partitioned into four new haploid daughter cells.
