1. Assume you identify a recessive mutation in the AP endonuclease in yeast. During the diploid phase of their lifecycle, the yeast are viable but haploid strains die rapidly. Why might this be? 2. (a). What is the difference between germline and somatic mutations? (b) name at least one way that each […]

Why is water able to move across the dialysis membrane but sucrose is not. Explain why this is the case. 1.) Water is attracted to pores in the membrane because of its polarity. 2.) Sucrose was immobilized because it adhered to the membrane. 3.) The sucrose molecule is smaller than […]

Q. Two different strains of fies are each homozygous for different recessive mutant alleles of the short wing gene (sw^1 ans sw^2). Strain 1 is also heterozygous for dominant green-eye mutant allele (G); Strain 2 is also heterozygous for a dominant hairy leg mutant allele (H). All three genes (G, […]

4. Synthesis of fatty acids needs the movement of citrate out of the mitochondria. This occurs under conditions of high levels of acetyl CoA which is needed to stimulate the activity of:-pyruvate carboxylase-pyruvate dehydrogenase-isocitrate dehydrogenase5. which of the following activators is correctly paired with the glycolytic or gluconeogenic enzyme that […]
