In what stage of mitosis does DNA replication occur?

S phase
M phase (mitosis) is usually followed by cytokinesis. S phase is the period during which DNA replication occurs.

Does DNA replication take place in mitosis?

Yes, DNA replicates in both mitosis and meiosis. In meiosis, the cell undergoes two divisions, i.e. meiosis I and II. Meiosis I is reduction division and meiosis II is similar to mitosis but DNA replicates only once during meiosis, i.e. before meiosis I in S phase.

Where does DNA replication occur before mitosis?

interphase
Yes, DNA replication occurs at the interphase, during S-stage of the cell cycle. The cell cycle consists of 4 stages, they are G1, S, G2 and M. Cell division occurs at M stage.

What phase does DNA replication occur in meiosis?

the S-phase
Yes, DNA replication occurs at the S-phase to produce identical sister chromatids. It is followed by two rounds of division to produce 4 haploid daughter cells.

What is G2 phase in mitosis?

G2 phase is a period of rapid cell growth and protein synthesis during which the cell prepares itself for mitosis. Curiously, G2 phase is not a necessary part of the cell cycle, as some cell types (particularly young Xenopus embryos and some cancers) proceed directly from DNA replication to mitosis.

What is replication and when does it occur?

Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. DNA replication is one of the most basic processes that occurs within a cell.

Why does DNA replication occur before mitosis and cell division?

Explanation: DNA replication needs to occur because existing cells divide to produce new cells. Each cell needs a full instruction manual to operate properly. So the DNA needs to be copied before cell division so that each new cell receives a full set of instructions!

Does DNA replication occur in G1 phase?

G1 phase. G1 is an intermediate phase occupying the time between the end of cell division in mitosis and the beginning of DNA replication during S phase. During this time, the cell grows in preparation for DNA replication, and certain intracellular components, such as the centrosomes undergo replication.

What is G1 and G2 phase in mitosis?

G1 phase (Gap 1) – Cellular contents excluding the chromosomes, are duplicated. II. S phase (DNA Synthesis) – Each of the 46 chromosomes are duplicated by the cell. III. G2 phase (Gap 2) – The Cell “double checks” the duplicated chromosomes for error, making any needed repair.
