After a cell undergoes dna replication
WebAfter replication, the chromosomes are composed of two linked sister chromatids. When fully compact, the pairs of identically packed chromosomes are bound to each other by cohesin proteins. The connection between the sister chromatids is closest in a region called the centromere. WebFeb 15, 2015 · After three rounds of replication, there will be eight cells: 2 3=8. After the first round, each cell will have one labeled strand and one not labeled. After the second round, two cells will have one labeled and one unlabeled strand, and two cells will have both strands labeled. After the third round, six cells will have both strands labeled.

WebIf the initial quantity of DNA in the cell is denoted as 2N, then after replication it becomes 4N. However the number of chromosomes does not vary, viz., if the number of chromosomes during G1 phase was 2n, it will remain 2n at the end of S phase. The centriole also divides into two centriole pairs in the cells which contain centriole. WebCells undergoing cell division proceed through a series of precisely timed and carefully regulated stages of growth, DNA replication, and division that produces two identical (clone) cells.
