In an animal cell there is a diploid set of chromosomes 8. Determine the amount of DNA

In an animal cell there is a diploid set of chromosomes 8. Determine the amount of DNA before mitosis, after mitosis, after the first and second division of meiosis.

Before any division, the interphase process takes place in the cell. In this case, the amount of DNA in chromosomes doubles. Since there is one DNA molecule in each chromosome, then eight times two will be sixteen.

The biological significance of mitosis is the preservation of the number of maternal chromosomes and DNA. In this case, eight.

Meiosis is division with a decrease in the number of DNA. After the first division – sixteen we divide by two – the total is eight, after the second division – eight we divide by two – four.
