How many chromosomes will the cell have at g1
WebHowever, during the G 1 stage, the cell is quite active at the biochemical level. The cell is accumulating the building blocks of chromosomal DNA and the associated proteins as well as accumulating sufficient energy … WebWe have a cell with chromosome number 4 at G1. At G1 phase: No. of DNA molecule =4 No. of chromosome=4 and each chromosome has a single chromatid At G2 phase: In S phase DNA replicates. So no. of DNA molecule in G2 will be =8 No. of chromosome= 4 and as two DNA molecules are held at a common centromere.

Did you know?
WebThe number of chromosomes becomes haploid in meiosis I, because the actual sister chromatids are not pulled apart by spindle fibers. For example, if a cell was undergoing meiosis, and had a total of 4 chromosomes in it, then 2 of them would go to one daughter cell, and 2 of them would go to the other daughter cell. That makes 2 haploid cells. WebFeb 8, 2024 · However, extra or supernumerary non-essential chromosomes, termed B chromosomes, have been detected in numerous plant and animal species [1,2,3,4]. The frequency of B chromosomes within a given population can range from very low to complete fixation among all individuals, and a carrying individual can contain one to as many as ten …
WebJul 17, 2024 · At the end of the meiotic process, four daughter cells are produced. G1 phase: The period prior to the synthesis of DNA. In this phase, the cell increases in mass in preparation for cell division. Note that the G in G1 represents gap and the 1 represents first, so the G1 phase is the first gap phase. WebChromosomes are made up of DNA and are the carriers of genetic information. Human beings typically have 23 pairs of chromosomes, for a total of 46 chromosomes. Each pair …
