- What is the reduction division? Why is it necessary??How many functional copies of ɑAA reductase does a yeast cell need in order to perform lysine biosynthesis in a haploid cell? In a diploid cell?Schizosaccharomyces pombe, also known as "fission yeast," is a powerful model organism in molecular and cell biology. While performing a genetic screen, you discover an auxotrophic S. pombe strain that is unable to synthesize one or more vitamins. The following table represents the key experiments you performed during your genetic screen. Fill in the table with the outcome of each experiment for your mutant strain (using + for growth and - for no growth). Medium Rich media Minimal media Minimal media + all vitamins Minimal media + all amino acids Growth Wild-type + + + + Mutant + + + > > >
- Draw a schematic diagram showing the components involved in the regulation of the tryptophan оperon.You are studying the M-cyclin. You treat mitotic cells with an inhibitor of the proteasome and find that M-cyclin is no longer degraded and that this prolongs mitosis. You also find that in the presence of the inhibitor, M-cyclin is now running slower/larger in a Western than you have previously observed. In 1-2 sentences, explain why this might be happening.

- What is the simplest explanation for why patients have been identified with only one copy of the phosphofructokinase-1 gene (heterozygous), but no patients have been identified that lack both copies of the phosphofructokinase-1 gene (homozygous)? Patients lacking both copies of the phosphofructokinase-1 genes will be found once DNA sequencing technology can sequence whole genomes. Phosphofructokinase-1 is needed for nitrogen metabolism and there are no enzymes to replace this function, so cells die from ammonia toxicity. Phosphofructokinase-1 is a required enzyme for carbohydrate metabolism in all living cells, complete loss of this enzyme would be lethal. There are 6 phosphofructokinase-1 paralogous genes in humans and it is impossible to lack both type 1 copies when there are also types 4, 5, and 6.In humans, why is it that the mother transmits nearly all of the extranuclear genes to her children?If GUS is present in the Arabidopsis Thaliana plant , what does that mean ? What are the explained results ?
- Explain a mechanism for how a nuclear-encoded protein is targeted to the inner membrane of the mitochondrion. Explain the mechanism for how a nuclear-encoded protein is targeted to the thylakoid membrane.
