WebThe region of the chromosomes where the two copies are held together after DNA replication. This may be near the center of v Cohesin chromosome. E. The microtubule-based triplet structure within the "central body" that nucleates formation of new microtubules. F. One of two identical copies of a chromosome after duplication. G. WebDNA replication occurs during the S Phase. When the DNA amount was, suppose, x, the chromosome was in the form of a single chromatid. After replication of the DNA, it becomes 2x, and the chromatid doubles. The two sister chromatids remain attached at the centromere, and comprise one single chromosome.
WebJan 16, 2024 · After the completion of replication, each DNA molecule would have one parental and one newly synthesised strand. This shows that the replication of DNA is a semiconservative process.

WebThe coples are the same size and shape, they carry the same sets of genes, and they have identical information for each gene. These copies are connected together at a region called the centromere and are called sister chromatids This image shows a pair of homologous chromosomes after DNA replication. WebThere are specific chromosomal locations called origins of replication where replication begins. In some eukaryotes, like yeast, these locations are defined by having a specific sequence of basepairs to which the replication initiation proteins bind.
WebOct 7, 2024 · Before DNA can be replicated, the double stranded molecule must be “unzipped” into two single strands. DNA has four bases called adenine (A), thymine (T), cytosine (C) and guanine (G) that form pairs …
