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.
Are sister chromatids present in G1 phase of the cell cycle?
Sister chromatids are present in G1 phase of the cell cycle following DNA replication in S phase. Sister chromatids are two identical copies of a chromosome joined together at the centromere. During G1 phase, the cell prepares for DNA replication in the subsequent S phase.
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.
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.
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.
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.
During which phase of the cell do sister chromatids first appear?
S phase
Are sister chromatids present in G1 phase of the cell cycle?
Sister chromatids are present in G1 phase of the cell cycle following DNA replication in S phase. Sister chromatids are two identical copies of a chromosome joined together at the centromere. During G1 phase, the cell prepares for DNA replication in the subsequent S phase.
Which phase of mitosis do the sister chromatids separate at their centromeres?
anaphase
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.

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 is it when sister chromatids can be seen for the first time?
metaphase
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.
During what phase do the centromeres of sister chromatids disjoin and the chromatids separate?
During the anaphase stage of mitosis, the centromeres of sister chromatids disjoin and the chromatids are pulled apart to opposite ends of the cell by the spindle fibers.
What phase do cohesins join sister chromatids of duplicated chromosome?
Cohesins join sister chromatids during the S phase of the cell cycle. This is when DNA replication occurs, resulting in the formation of identical sister chromatids bound together by cohesin proteins.
Chiasmata form between.?
Sister chromatids
During what phase does the sister chromatids line up in the midplane of the cell?
During Mitosis, the spindle pulls apart the sister chromatids of the chromosome in the Anaphase stage.
