Question
GAL4 UAS GAL80 TATA In the absence of galactose, GAL80 blocks GAL4 from Basal transcription apparatus activating transcription. GAL3 Galactose GAL4 TATA 3 GAL4 can now interact with basal transcription apparatus GAL80 GAL3 2 when galactose is present, and stimulate transcription. it binds to GAL3 and brings about a change in the Galactose conformation of GAL80 Figure 17.7 Genetics: A ConceptualApproach, Fifth Edition 2014 H. Freemanand Company Figure 17.7 Transcription is activated by GAL4 in response to galactose. GAL4 binds to the UASG site and controls the transcription of genes in galactose metabolism.Explanation / Answer
Answer of the following given Question-
gal3 block gal80 which leads to Gal4 intract with basal transcrition apparatus lead to block gene expression.
Gal 3 mutate then Gal-3 unable tobind gal80 so gal 80 is free to bind gal-4 then gal 4 is not able to interation basal transcripion factor and then basal transctription factor increase gene expression
