The way by which deletion within the GAL4 gene would affect transcription of the yeast GAL1 gene in the presence of galactose. Introduction: Transcription is the process of formation of RNA (ribonucleic acid) from the complementary DNA (deoxyribonucleic acid). GAL genes are required for the proper growth of yeast in galactose medium. The regulation of GAL genes is regulated by the products of GAL4, GAL8, and GAL3 genes. Mutation in these regions may disrupt the process of transcription in yeast.

Students have asked these similar questions

The shape of radishes may be long (SL/SL), oval (SL/SS), or round (SS/SS), and the color of radishes may be red (CR/CR), purple (CR/CW) or white (CW/CW). If a long, red radish plant is crossed with a round, white plant, what will be the appearance of the F1 and F2 generations?

None

Question #3: In the KeyGene paper, the authors state that it would be useful if pollen from an apomict would transmit apomixis-inducing genes to the female in the cross (assuming the pollen is viable). Assuming there was just one gene conferring gametophytic obligate apomixis, and that the two parents are inbreds, what would be the consequences of such a cross if: a) The apomixis was a dominant trait? Indicate the genotypes and phenotypes (apomict or non- apomict) of the parents, F1 and F2 generations. Remember to include the expected genotypic and phenotypic ratios (or percentages) in the F1 and F2 generations, and to position the female first (left side) in the parental cross. b) The apomixis was a recessive trait? Indicate the genotypes and phenotypes (apomict or non- apomict) of the parents, F1 and F2 generations. Remember to include the expected genotypic and phenotypic ratios (or percentages) in the F1 and F2 generations, and to position the female first (left side) in the…
