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.
Mitosis has 5 phases:
.Prophase
.Prometaphase
.Metaphase
.Anaphase
.Telophase
DNA replication (chromosome replication) occurs only once before mitosis or meiosis.

In which phase does chromosome replication occur?
Chromosome replication occurs during the S phase of the cell cycle. This is when DNA is synthesized to ensure that each daughter cell receives an identical copy of the genetic material during cell division.
Which does not occur during meiosis?
DNA replication does not occur during meiosis. Meiosis is a specialized cell division process that involves two rounds of division to produce gametes with half the number of chromosomes as the parent cell. DNA replication happens during the interphase preceding meiosis.
The sites where DNA replication and separation occur is called?
The sites where DNA replication and separation occur are called the replication fork, which is formed during DNA replication when the double-stranded DNA is unwound, and the centromere, which is the region of a chromosome where sister chromatids are held together before separation during cell division.
How often in the life of a cell does replication occur?
Cell replication can occur at different rates depending on the cell type. In general, cell replication can range from a few hours to a few days. For example, skin cells replicate every few weeks, while intestinal cells replicate every few days.
After replication each chromosome harbors what?
After replication, each chromosome harbors two sister chromatids, which are identical copies of the original chromosome. The sister chromatids are held together at the centromere and will later separate during cell division.
In which phase does chromosome replication occur?
Chromosome replication occurs during the S phase of the cell cycle. This is when DNA is synthesized to ensure that each daughter cell receives an identical copy of the genetic material during cell division.
Does chromosome replication occur in mitosis and meiosis?
Chromosome replication occurs before both mitosis and meiosis. During the S phase of the cell cycle, DNA is replicated in preparation for cell division. In mitosis, replicated chromosomes are separated into two identical daughter cells, while in meiosis, replicated chromosomes are separated twice to produce haploid gametes.
Where the cell does DNA replication take place?
DNA replication takes place in the chromosome which is located in the nucleus of a cell.
Which does not occur during meiosis?
DNA replication does not occur during meiosis. Meiosis is a specialized cell division process that involves two rounds of division to produce gametes with half the number of chromosomes as the parent cell. DNA replication happens during the interphase preceding meiosis.
The sites where DNA replication and separation occur is called?
The sites where DNA replication and separation occur are called the replication fork, which is formed during DNA replication when the double-stranded DNA is unwound, and the centromere, which is the region of a chromosome where sister chromatids are held together before separation during cell division.

When does chromosomal replication occur?
Chromosomal replication occurs during the S phase of the cell cycle, which is part of interphase. During this phase, the DNA in a cell is replicated to ensure that each daughter cell will receive a complete set of chromosomes.
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.
Where in the cell does DNA take place?
DNA replication takes place in the chromosome which is located in the nucleus of a cell.
Where does DNA replicate take place in the cell?
DNA replication takes place in the chromosome which is located in the nucleus of a cell.
Where does DNA replication occur within a cell?
The Nucleus
What is the result of normal chromosome replication?
Normal chromosome replication results in two identical copies of the original chromosome, each with one chromatid. This process ensures that each daughter cell receives a complete set of chromosomes during cell division.
