Nonsense upstairs. Have you studied biology? The biology I studied in college should be a good explanation for this problem. What is a chromatid, that is, a replicated chromosome? Can chromosomes be DNA? Jokes. . Secondly, cytosol is a part of teaching materials and counseling, but the university did not say this term. We are talking about cytosol, which is the liquid part of cytoplasm except organelles, and it is the place of cell metabolism, which coincides with ribosomes rather than organelles. . I hope my study will make progress.
