Chromosomes replicated
WebThis is what it enters into. But if the cell checks it and it says you're big enough you're ready to replicate. It goes onto the S. Phase and this is the DNA replication phase. And so the sister chroma tides are made here because they are the copy of the same chromosome. So you have a chromosome here and it gets replicated. Weba replicated chromosome has two identical DNA molecules (sister chromatids) attached at the centromere. N = number of different types of chromosomes in a cell 1N = haploid = one set; 2N = diploid = two sets eg., In humans, the haploid sperm has 23 chromosomes; haploid egg has 23; diploid embryo has 46 chromosomes.
