Do chromatids form when DNA replicates prior to cell division?
Yes, chromatids form when DNA replicates prior to cell division. During the S phase of the cell cycle, each chromosome is duplicated, resulting in two identical copies called sister chromatids. These chromatids are connected at a region known as the centromere until they are separated during cell division. This process ensures that each daughter cell receives an identical set of chromosomes.
What are the two copies of DNA on each chromosome that form just before cell division?
The two copies of DNA on each chromosome that form just before cell division are called sister chromatids. Sister chromatids are identical copies of the original chromosome that are created during DNA replication in the S phase of the cell cycle. They are held together by a structure called the centromere.
During which phase of the cell cycle do chromatids form?
When a single chromosome is replicated, two sister chromatids are produced. After cell division, each of the chromatids is a chromosome for the daughter cell.
What contains uncondensed chromosomes that have been duplicated?
The nucleus of a cell contains uncondensed chromosomes that have been duplicated. During the interphase of the cell cycle, before cell division, the chromosomes replicate and form sister chromatids that are still uncondensed and spread throughout the nucleus.
What phase is occurring when chromatids are separate and a visible line forms between sets of chromatid?
The phase occurring when chromatids are separated and a visible line forms between sets of chromatids is called anaphase. During anaphase, the sister chromatids are pulled apart toward opposite poles of the cell by the spindle fibers. This separation ensures that each new daughter cell will receive an identical set of chromosomes during cell division. The formation of the visible line indicates the cleavage furrow beginning to form as the cell prepares for cytokinesis.
What phase do sister chromatids form?
The sister chromatids first appear in the S phase of the cell cycle.
During the s phase chromosomes are converted to what form?
During the S phase of the cell cycle, chromosomes are replicated to form sister chromatids. Sister chromatids are two identical copies of a single replicated chromosome that are held together by a centromere.
How many chromatids in 1 chromosomes before interphase?
There are two chromatids in each chromosome before interphase, as each chromosome replicates during the S phase of the cell cycle to form sister chromatids that are connected at the centromere.
Do chromatids form when DNA replicates prior to cell division?

Sister chromatids are identical copies of the original chromosome that are created during DNA replication in the S phase of the cell cycle. They are held together by a structure called the centromere.
What happens to the chromosomes during S-phase?
The S-phase is during interphase, which means there are no chromosomes. DNA is replicated in the S-phase ("s" for synthesis). It can only be replicated in the form of chromatin, not wrapped up in chromosomes.
What changes occur in chromosomes before and after the S phase of the cell cycle?
Before the S phase of the cell cycle, chromosomes are in a condensed form and consist of a single chromatid. During the S phase, DNA replication occurs, resulting in the formation of two identical sister chromatids joined at the centromere. This process increases the amount of genetic material in the cell.
During which phase of the cell cycle do chromatids form?
When a single chromosome is replicated, two sister chromatids are produced. After cell division, each of the chromatids is a chromosome for the daughter cell.
Have the chromosomes in the locust testes divided into chromatids?
Yes, in locust testes, as in other organisms, chromosomes undergo division and replicate to form chromatids during the cell cycle, specifically during the S phase of interphase. Each chromosome is duplicated, resulting in two sister chromatids held together at the centromere. During meiosis, these chromatids will eventually be segregated into gametes, contributing to genetic diversity. Thus, in the testes of locusts, the chromosomes do indeed divide into chromatids as part of their reproductive cell development.
What contains uncondensed chromosomes that have been duplicated?
The nucleus of a cell contains uncondensed chromosomes that have been duplicated. During the interphase of the cell cycle, before cell division, the chromosomes replicate and form sister chromatids that are still uncondensed and spread throughout the nucleus.

This separation ensures that each new daughter cell will receive an identical set of chromosomes during cell division. The formation of the visible line indicates the cleavage furrow beginning to form as the cell prepares for cytokinesis.
Which is the phase of mitosis during which sister chromatids separate into individual chromosomes?
Anaphase is the phase of mitosis where sister chromatids separate and move towards opposite poles of the cell. This marks the transition from the duplicated chromosome state to individual chromosomes.
