WebIn the first step, called interphase, the DNA strand of a chromosome is copied (the DNA strand is replicated) and this copied strand is attached to the original strand at a spot called the centromere. This new structure is called a bivalent chromosome. WebAll the replicons of a single chromosome do not begin to replicate simultaneously since the initiation of the replication occurs at different times. Certain chromosomes and parts of a single chromosome replicate early while the others may replicate later during the S-phase.

WebOct 1, 2024 · Chromosomes can exist in duplicated or unduplicated states. At the beginning of mitosis, for example, a chromosome consists of two sister chromatids – chromatids are the term used to describe the chromosome in its duplicated state. WebThere are two main properties of homologous chromosomes: 1) the length of chromosomal arms and 2) the placement of the centromere. [4] The actual length of the arm, in accordance with the gene locations, is …

WebRemember, I can draw Mal's genotype like this: Given that Mal's chromosomes before replication looked like the above (genotype C6CR ), after mitosis what would the chromosomes in the daughter (new) cells look like? (1 mark) If the drawing is unclear to you, you can use the genotypes below to answer the question too: - A) genotype is C 6C … WebThe reason is simple, before replication, chromosome has one chromatid, after S phase or replication. The DNA content is doubled. So chromosome has two chromatids after replication. It is very simple to count number of DNA molecules or chromosome during different stages of cell cycle. Rule of thumb:
