The chromosmes beging te replicate in the S stage.
II
prophase!
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.
Chromosomes are replicated during DNA replication, which occurs during interphase.
S phase or Synthesis.
There are 46 individual chromosomes (not sister chromatids) in human cells. In G2 they replicate and 46 pairs of sister chromatids are present
The S phase of the cell cycle
Chromosomes replicate when DNA replicates during the S phase (synthesis) of of the cell cycle.
Before mitosis begins, the chromosomes in a cell replicate. This occurs during the S (synthesis) phase. Chromosomes need to replicate so that when the cell divides at the end of mitosis, the daughter cells each recieve a copy of the chromosomes.
Chromosomes are replicated during DNA replication, which occurs during interphase.
It is a phase of the reproductive cycle of a cell. It is the part where the centrioles have separated and are drawing the chromosomes apart into two cell halves before they replicate the cell as a haploid or a diploid, depending on whether is a somatic cell or a sex cell.
Strictly speaking, the chromosomes are not copied during mitosis but already before cell division takes place. This phase is called INTERPHASE and is again divided into three phases, G1 (first gap), S (synthesis), and G2 (second gap). The replication of chromosomes only happens in the S phase.
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.
Interphase. Cells spend the majority of the time in interphase, where they grow and perform their life functions.
Chromosomes replicate during cell division, so are present as a new cell forms.
Chromosomes are found in the nucleus of a cell and the function of chromosomes is to hold the genes (made form DNA) and to replicate the genes when a cell divides.
Chromosomes are replicated during DNA replication, which occurs during interphase.
