When before a cell enters mitosis what happens to the genetic information in that cell?
Before a cell enters mitosis, its genetic information undergoes replication during the S phase of the cell cycle. This process results in the duplication of each chromosome, producing two identical sister chromatids for each chromosome. Additionally, the cell performs various checks to ensure that the DNA is intact and properly replicated, preparing for the accurate segregation of genetic material during mitosis.
How many DNA molecules are in a chromosome just before mitiosis?
Just before mitosis, a chromosome consists of two sister chromatids joined by a centromere. Each sister chromatid contains one DNA molecule. Therefore, there are two DNA molecules in a chromosome just before mitosis.
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
A single strand of the chromosome pair formed in early mitosis?
In early mitosis, each chromosome consists of two identical sister chromatids joined at a region called the centromere. Before mitosis begins, during the S phase of interphase, DNA replication occurs, resulting in the formation of these sister chromatids. Thus, a single strand of a chromosome in this context refers to one of the sister chromatids, which will eventually be separated and distributed to the daughter cells during mitosis.
What must happen to a chromosome before the next mitosis cycle starts?
Before the next mitosis cycle starts, the chromosome must replicate during the S phase of interphase to form sister chromatids. This ensures that the daughter cells will receive an exact copy of the genetic material during cell division.

When are chromosome duplicate before or during mitosis?
Chromosomes are duplicated before mitisis in S phase of inter phase .
What happens to the chromosome number during mitosis?
During mitosis, the chromosome number remains the same. The cell duplicates its chromosomes before dividing, so each daughter cell receives the same number of chromosomes as the parent cell.
Do chromosomes duplicate during metaphase in the cell cycle?
Chromosomes do not duplicate during metaphase in the cell cycle. Chromosome duplication occurs during the S phase of interphase, before the cell enters mitosis. During metaphase, the duplicated chromosomes align at the center of the cell before separating into two daughter cells during anaphase.
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
Why must DNA duplicate before mitosis began?
Because mitosis is the process of duplicating a cell. Creating 2 daughter cells out of 1 parents cell. And the duplication of the DNA is just the first step.
If the chromosome number of a typical onion root tip cell is sixteen before mitosis what is the chromosome number of the each newly formed nucleus after nuclear division has taken place?
the same as before, each will have sixteen. If it was meyoses it would be 1/2 that (8) Mitotic division creates exact replicates of the original, so the answer is 16. Meosis occurs in the flower of the onion, it's sex cells ovules and pollen will have only 8 chromosomes
How many rounds of chromosome replication occur in the cell?
One round of chromosome replication occurs in the cell during the S phase of the cell cycle. This results in each chromosome being duplicated, producing two identical DNA molecules called sister chromatids that are connected at the centromere.
What 3 stages are replicated before mitosis?
The three stages before mitosis are the G1 S and G2 phases. In the G1 phase the cell grows, in the S phase the cell replicates its DNA, and in the G2 phase the cell grows again and replicates/ makes any organelles required for mitosis.
