Answer: Telophase
Explanation:
It starts to separate in anaphase but pinches at telophase sinc it’s the last phase before seperation
Answer:
Explanation:
we have three strains.
the first is the wild type which has tryptophan mRNA which gets degraded rapidly and tryptophan synthase which is stable. therefore, in the presence of tryptophan, no new mRNA is formed and whatever tryptophan synthase was present would be diluted out as cells continue to divide.
Strain A has stable mRNA and stable tryptophan synthase. so since the mRNA is present, new enzyme will continue to form from it. However, since no new mRNA is formed, the enzyme activity will get diluted as cells divide, but at a much slower rate than the wild type.
in Strain B , synthase is rapidly degraded and no new mRNA is formed. so the tryptophan synthase activity would decrease drastically.
Answer:
Lysine and AAG
Explanation:
AAA in the table codes for AAA, which is Lysine. Also, AAG also codes for Lysine, which would be a silent mutation.
