What is the first event to occur during DNA replication?

DNA replication occurs during mitosis and meiosis. During this process, the DNA is lined up before being duplicated so that each cell that's created from the process has the DNA needed.


When does replication occur during meiosis?

Interphase


Does cell growth and replication continue through the cell cycle?

No. Cell growth and DNA replication occur during interphase but do not occur during mitosis and cytokinesis.


Which in DNA often occur during replication. During which phase of the cells cycle do such mutations occur?

Interphase


Can Mutations can spontaneously occur during DNA replication?

Yes


Mutations in DNA often occur during replication During which phase of the cell cycle do such mutations occur?

Where does mitosis process?

DNA replication during interphase occurs in the nucleus. All other phases of mitosis occur in the cytoplasm after the nuclear membrane is disassembled.


Where D-loop replication is done?

D-loop replication mostly takes place during DNA-replication. But it also can occur in telomeres and mitochondria.


Duplication of chromosomes occur in?

The replication of the chromosomes occurs during interphase.


What are the two process that closely occur in mitosis?

Replication of DNA and separation of sister chromosomes.


In what part of the cell does the replication occur?

DNA replication occurs during Interphase. This is not normally part of the cell division cycle but interphase must occur before subsequent stages such as prophase and metaphase can occur.


When does chromosomal replication occur?
