Kinesin-5 is a motor protein that binds to overlapping interpolar microtubules near the midzone of the mitotic spindle. each of these kinesin proteins has two motor domains that walk toward the plus ends of the microtubules to which the kinesin is bound. when is this kinesin active and how does it affect the spindle? choose one: o a. during anaphase a, kinesin-5 slides the microtubules past one another toward the spindle poles, pulling the poles together and shortening the spindle. o b. during anaphase b, kinesin-5 slides the microtubules over one another toward the spindle equator, pulling the poles together and shortening the spindle. o c. during anaphase b, kinesin-5 slides the microtubules past one another toward the spindle poles, pushing the poles apart and lengthening the spindle. d. during anaphase a, kinesin-5 slides the microtubules past one another toward the spindle poles, pushing the poles apart and lengthening the spindle. © e. during anaphase b. kinesin-5 slides the microtubules past one another toward the spindle poles, pulling the poles together and shortening the spindle.

Considering the yellow and green pea color phenotypes studied by gregor mendel: a. what is the biochemical function of the protein that is specified by the gene responsible for the pea color phenotype? (1 point) b. a null allele of a gene is an allele that does not specify (or encode) any of the biochemical function that the gene normally provides (in other words, either no protein at all or only non-functional protein is produced from it). of the two alleles, y and y, which is more likely to be a null allele? (1 point) c. in terms of the underlying biochemistry, why is the y allele dominant to the y allele? (2 points) d. why are peas that are yy homozygotes green? (1 point) e. the amount of protein produced from a gene is roughly proportional to the number of functional copies of the gene carried by a cell or individual. what do the phenotypes of yy homozygotes, yy heterozygotes, and yy homozygotes tell us about the amount of sgr enzyme needed to produce a yellow color? explain your reasoning.
