In what phase of mitosis does DNA replication occur?
DNA replication occurs during the S phase of the cell cycle, which is before mitosis begins.
How many chromosomes were present in the nucleus when mitosis began?
Before mitosis begins, a cell has a diploid number of chromosomes, which means there are two sets of chromosomes. This is because during interphase, before mitosis begins, the DNA has already replicated, so the cell contains identical copies of each chromosome.
During what part of the mitosis does the DNA replicate?
The DNA replicates during the S phase of the cell cycle, which occurs before mitosis starts. DNA replication ensures that each daughter cell receives a complete set of genetic information during cell division.
What two paired cell structures are copied before mitosis begins?
Chromosomes are copied in the form of sister chromatids during S-phase of the cell cycle, which are then separated during mitosis. The centrioles also duplicate before mitosis begins to ensure proper formation of the mitotic spindle and accurate segregation of chromosomes.
Before mitosis begins which happens before the nucleus starts dividing?
During interphase, which precedes mitosis, the cell grows and replicates its DNA in the nucleus. This prepares the cell for division by ensuring that each daughter cell receives a complete set of genetic material.
When does a cell's DNA get replicated?
During S phase Right before mitosis begins
What begins the cells before the mitosis?
the stage before mitosis is called interphase and majority of the time the cell has is spent in interphase. during interphase the cell acquires nutrients and the DNA replicates.

What thing is when mitosis begins?
The process of mitosis starts off with a Diploid (2N) cell.
During what part of the mitosis does the DNA replicate?
The DNA replicates during the S phase of the cell cycle, which occurs before mitosis starts. DNA replication ensures that each daughter cell receives a complete set of genetic information during cell division.
What two paired cell structures are copied before mitosis begins?
Chromosomes are copied in the form of sister chromatids during S-phase of the cell cycle, which are then separated during mitosis. The centrioles also duplicate before mitosis begins to ensure proper formation of the mitotic spindle and accurate segregation of chromosomes.
What begins to stretch across the cell during mitosis?
the cellmembrane?
Before mitosis begins which happens before the nucleus starts dividing?
During interphase, which precedes mitosis, the cell grows and replicates its DNA in the nucleus. This prepares the cell for division by ensuring that each daughter cell receives a complete set of genetic material.
Does mitosis start with one diploid cell?
Yes, mitosis typically begins with a single diploid cell that contains two copies of each chromosome. During mitosis, this cell divides into two daughter cells that are genetically identical to the parent cell.
Why are chromosome called doubled chromosomes just before mitosis begins?
Just before cell division begins,the amount of DNA doubles and so do the chromosomes.Each doubled chromosome consists of two copies of the original chromosome joined at the center
