Interphase. Cells spend the majority of the time in interphase, where they grow and perform their life functions.
Chromosomes replicate when DNA replicates during the S phase (synthesis) of of the cell cycle.
The S phase
The prophase stage and the telophase stage of the cell cycle are similar in two ways. During both stages, cells have a complete set of chromosomes and organelles.
The stage in the cell cycle where DNA is replicated is actually in interphase, before the nuclear membrane dissolves in prophase. * The DNA is replicated at mid-interphase (in the S phase), between the two growth phases (G1 and G2). So replication precedes division by several hours in a typical cell.
Two sets of chromosomes must be available before mitosis so that each of the two daughter cells will have an entire set of chromosomes
In prophase stage, the replicated chromosomes condense and the nuclear envelope disappears. Earlier in prophase, chromatin visible condenses into the chromosomes.
During the S (synthesis) stage - after G1 and before G2.
Metaphase
Chromosomes replicate when DNA replicates during the S phase (synthesis) of of the cell cycle.
technically the chromosomes copy during interphase right before metaphase I of meiosis I so during Meiosis I the chromosomes are duplicated and not until metaphase II during meiosis II are the sister chromatids separated.
Yes - interphase includes a synthesis stage (often called the 'S phase'), which comes after G1 and before G2. This is when the chromosomes are replicated.
DNA is replicated in the Synthesis stage of the cell cycle.
DNA is replicated during interphase, and chromosomes form or condense during the prophase. So the genes and chromosomes are duplicated at the beginning of mitosis, during the interphase, although you can't see them as chromosomes until the prophase, before the cell splits.
The prophase stage and the telophase stage of the cell cycle are similar in two ways. During both stages, cells have a complete set of chromosomes and organelles.
Okay, so a pigeon has 80 chromosomes when its cells are in the diploid stage. In the haploid stage the cells have 40 chromosomes.
Meiosis Stage II.
If you are referring to the stages of life cycle for cells it would be in Interphase which is the stage in which most cells spend the majority of their time.
From stage of the cell cycle do cells somtimes exit?
