Question

1) В исходных соматических клетках кошки домашней 38 хромосом. Сколько хроматид (в сумме) будет в таких клетках в конце профазы митоза: а)38 б)19 в)76 г)152

Answer 1

В соматических клетках 2n=38 (хромосомы)
4c=76 хроматид

Answer 2

Answer:

In the somatic cells of domestic cats, there are 38 chromosomes. During the end of the prophase of mitosis, the number of chromatids in these cells would be 76.

Explanation:

During the prophase of mitosis, the chromosomes replicate, resulting in two sister chromatids for each chromosome. Since the somatic cells of domestic cats have 38 chromosomes, the total number of chromatids at the end of the prophase of mitosis would be 38 (original chromatids) * 2 (replicated sister chromatids) = 76 chromatids.
