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.
It is Fructose enters the glycolytic pathway in the liver then
the fructose 1-phosphate pathway. There are no catabolic pathways to metabolize
galactose, so the approach is to convert galactose into a metabolite of
glucose. Galactose is apply into glucose 6-phosphate in four steps.
Answer:
Gravity is considered to be one of the universal forces inherent of nature itself. Gravity is an attractive force between objects, which is proportional to the mass of the objects and inversely proportional to the distance between them. Gravity is what help planets follow an elliptical orbit, and is the reason why we can keep our feet on the surface of the earth.
