The photos below show flowers from two Arabidopsis plants. The plant on the left is wild-type (unmutated); the other carries a mutation that causes its flowers to have sepals and petals instead of stamens and carpels. The mutation inactivated one of the plant's ABC floral identity genes. Refer to Figure 10.8 and decide which gene (A, B, or C) has been inactivated.
6. Suppose a particular gene is required for early development and also later for development of a particulartissue, such as the adult nervous system. By generating a homozygous mutant clone in that tissue of a heterozygote, researchers can circumvent the lethalitythat would result if the entire animal is homozygousfor a loss-of-function mutation in that gene.A technique called MARCM (Mosaic Analysiswith a Repressible Cell Marker) was developed to enable Drosophila geneticists to generate homozygousmutant cell clones that are marked by the presence of areporter protein such as GFP. Marker expression enables the investigator to observe clearly the mutantphenotype within a clone of mutant cells. This technique relies on a yeast protein called Gal80 that is anegative regulator of the Gal4 protein described previously in Solved Problem II. Gal80 binds to Gal4 andprevents it from activating transcription. The idea ofMARCM is that Gal4/UASG-driven GFP expression isblocked by Gal80 throughout…

Many human cancers result when a normal gene mutates and leads to uncontrolled growth (a tumor). Genesthat cause cancer when they mutate are called oncogenes. Chemotherapy is effective against many tumorsbecause it targets rapidly dividing cells and kills them.Unfortunately, chemotherapy has many side effects,such as hair loss or nausea, because it also kills many ofour normal cells that are rapidly dividing, such as thosein the hair follicles or stomach lining.Many scientists and large pharmaceutical companiesare excited about the prospects of exploiting theRNAi pathway to selectively inhibit oncogenes in lifethreatening tumors. Explain in very general terms howgene-silencing therapy might work to treat cancer andwhy this type of therapy would have fewer side effectsthan chemotherapy
