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.
WHEN ARE CHROMOSOME (DNA) REPLICATED?
Interphase is when DNA replication occurs. :)
In both prokaryotes and eukaryotes how many copies of the chromosome are left after replication?
After replication, both prokaryotes and eukaryotes typically have two copies of each chromosome. In prokaryotes, which usually have a single circular chromosome, replication results in two identical circular DNA molecules. In eukaryotes, each linear chromosome is duplicated, producing two sister chromatids that remain attached at the centromere until cell division. Thus, in both cases, there are two copies present post-replication.
What type of mutation occurs when part of a chromosome is missing after replication?
Deletion
What is an original chromosome and its copy called?
An original chromosome is called a homologous chromosome, and its copy is called a sister chromatid. Homologous chromosomes have the same genes in the same order but may have different alleles, while sister chromatids are identical copies produced during DNA replication.
What is a duplicated chromosome?
A duplicated chromosome is a chromosome that has an exact copy of itself attached to it. This duplication occurs during the cell replication process and can lead to genetic abnormalities if not properly regulated. It can result in conditions like Down syndrome or cancers.
When are chromosome replicated?
Interphase is when DNA replication occurs. :)
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.

Where the cell does DNA replication take place?
DNA replication takes place in the chromosome which is located in the nucleus of a cell.
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.

What type of mutation occurs when part of a chromosome is missing after replication?
Deletion
Is down syndrome the result of a mutation on a gene?
No. It is due to a third chromosome (21) instead of just the normal two.
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.
What is an original chromosome and its copy called?
An original chromosome is called a homologous chromosome, and its copy is called a sister chromatid. Homologous chromosomes have the same genes in the same order but may have different alleles, while sister chromatids are identical copies produced during DNA replication.
