WebGene duplication (or chromosomal duplication or gene amplification) is a major mechanism through which new genetic material is generated during molecular evolution.It can be defined as any duplication of a region of … 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 …
WebIf a cell has 15 pairs of chromosomes (n = 15), it has 30 chromosomes (2n = 30). At the end of mitosis, the two daughter cells will be exact copies of the original cell. Each daughter cell will have 30 chromosomes. At the end of meiosis II, each cell (i.e., gamete) would have half the original number of chromosomes, that is, 15 chromosomes. 2. Webchromosomes until they are lined up at the spindle equator. There are 23 pairs of homologous chromosomes, or homologues, in each cell. After replication there are a total of 92 sister chromatids in each cell. There are 46 individual chromosomes in each cell. After replication there are a total of 46 chromosomes, with 92 individual
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. WebAfter DNA replication, the cells is still genetically diploid (2N chromosome number), but has 4X DNA content because each chromosome has replicated its DNA. Each …
