Chimpanzees have 48 chromosomes in their somatic cells. Determine the chromosome set and the number of DNA molecules in cells before the onset of meiosis, in the anaphase of meiosis I and in the prophase of meiosis II. Explain the answer in each case.
Before the onset of meiosis, the set of chromosomes and DNA is equal to 2n4c; at the end of the interphase, DNA was doubled, chromosomes became two-chromatid; 48 chromosomes and 96 DNA molecules. In anaphase of meiosis I, the number of chromosomes and DNA in the cell does not change and is equal to 2n4c. Haploid cells with a set of dichromatid chromosomes with a set of n2c enter the prophase of meiosis II; 24 chromosomes and 48 DNA molecules.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
