Does DNA replication occur in both mitosis and meiosis?

o, the correct statement is ‘In both mitosis and meiosis the replication of DNA and chromosomes occurs at the same stage.

Does DNA replication occur in meiosis?

Complete answer: In meiosis, DNA replication is followed by two rounds of cell division to produce four daughter cells. Each daughter cell has half the number of chromosomes as the original parent cell. The two meiotic divisions are known as meiosis I and meiosis II.

Which occurs in both mitosis and meiosis?

The separation of sister chromatids is the only item of the answer choices that occurs in both mitosis and meiosis. Prophase II and metaphase II only occur in meiosis, as does recombination between homologous chromosomes.

Where does DNA replication take place in meiosis?

Meiosis is the form of eukaryotic cell division that produces haploid sex cells or gametes (which contain a single copy of each chromosome) from diploid cells (which contain two copies of each chromosome). DNA replication takes place in S-phase of the Interphase before Meiosis I begins.

How many times DNA replication occurs in meiosis?

Note: The DNA replication occurs only once in both meiosis and mitosis although the number of cell divisions is two in meiosis and one in mitosis which results in the production of different numbers of haploid cells in both the process.

Is there DNA replication in mitosis?

This process involves replication of the cell’s chromosomes, segregation of the copied DNA, and splitting of the parent cell’s cytoplasm. … The outcome of binary fission is two new cells that are identical to the original cell.

What are 3 similarities and 3 differences between mitosis and meiosis?

Mitosis consists of one stage whereas meiosis consists of two stages. Mitosis produces diploid cells (46 chromosomes) whereas meiosis produces haploid cells (23 chromosomes). Mitosis produces two identical daughter cells whereas meiosis produces four genetically different daughter cells.

What are two similarities and two differences between mitosis and meiosis?

Mitosis produces two cells from one parent using one division event. But meiosis produces four new child cells with two divisions, each of which has half the genetic material of its parent. Mitosis takes place all over the body, while meiosis only takes place in the sex organs and produces sex cells.
