when are the chromosomes of a cell duplicated? - Lisbdnet.com

Duplications arise from an event termed unequal crossing-over that occurs during meiosis between misaligned homologous chromosomes. The chance of it happening is a function of the degree of sharing of repetitive elements between two chromosomes.

"WebThough it looks like there are two of each chromosome in each cell, these are duplicated chromosomes; ie, it is one chromosome which has been copied, so there is only one possible allele in the cell (just two copies of it). The second meiotic division is where sister (duplicated) chromatids separate. It resembles mitosis of a haploid cell. " - How do chromosomes duplicate

WebIt also duplicates a microtubule-organizing structure called the centrosome. The centrosomes help separate DNA during M phase. G _2 2 phase. During the second gap phase, or G _2 2 phase, the cell grows more, makes proteins and organelles, and begins to reorganize its contents in preparation for mitosis. G _2 2 phase ends when mitosis begins. WebThe chance of it happening is a function of the degree of sharing of repetitive elements between two chromosomes. The products of this recombination are a duplication at the site of the exchange and a reciprocal deletion. Ectopic recombination is typically mediated by sequence similarity at the duplicate breakpoints, which form direct repeats.

Usually, chromosome material telomeric to the breakpoints is lost and leads to an abnormal phenotype. Rings are commonly unstable mitotically and often form double ring structures. Isochromosomes arise when one part of the chromosome is duplicated and separated from the other.
