O A. Screen thousands of strains for a spontaneous unc-22 mutation
O B. Soak worms in mutagenic solutions of EMS and screen the progeny
OC. Inject antisense strands of unc-22 RNA into worm ovaries, which will be taken up by germ line cells and expressed in progeny
O D. Inject a high dose of unc-22 MRNA into worm ovaries, which will be taken up by germ line cells and expressed in progeny

- . An interesting mutation in lacI results in repressorswith 110-fold increased binding to both operator andnonoperator DNA. These repressors display a “reverse”induction curve, allowing β-galactosidase synthesis inthe absence of an inducer (IPTG) but partly repressingβ-galactosidase expression in the presence of IPTG. Howcan you explain this? (Note that, when IPTG binds a repressor, it does not completely destroy operator affinity,but rather it reduces affinity 110-fold. Additionally, ascells divide and new operators are generated by thesynthesis of daughter strands, the repressor must findthe new operators by searching along the DNA, rapidlybinding to nonoperator sequences and dissociating fromthem.)arrow_forward1 Gene 1 A 2 Gene 2 11 nm Chromatin fiberarrow_forwarda.

- Alignment of protein sequences from the HOX gene family identifies a highly conserved domain in the C-terminal part of the protein that is a domain (one acronym and one word). Although Hox genes have important roles during embryogenesis and tissue differentiation, the different HOX proteins bind to very similar DNA (one word) that are rich in the bases and (one word each). To ensure high affinity binding to (one acronym) and specific regulation of target (one word), the HOX proteins form complexes with (two words).arrow_forwardStrength 22.

- Hơ many mismatches would you expect to find between this sequence and the reference sequence? I know the answer is 3, can you please explain why?arrow_forwardWHAT IF? Since the results support a role for mouse FOXP2 invocalization, you might wonder whether the human FOXP2 protein is akey regulator of speech. If you were given the amino acid sequences ofwild-type and mutant human FOXP2 proteins and the wild-type chimpanzee FOXP2 protein, how would you investigate this question? What furtherclues could you obtain by comparing these sequences to that of the mouseFOXP2 protein?arrow_forward1. - Which factor(s)/protein(s) would you expect to occur at positions C and G ? (name them) 2. - Would you expect e1, e2, or e3 to be an enhancer for gene t? (explain briefly) 3. - Which genes would you expect to be most likely regulated by enhancer e1? (explain briefly) 4. - In this example genes t - x are expressed but genes y and z are not transcribed. At which position would you expect to see a sharp transition between the chromatin marks H3K27me3 and H3K36me3? (name the position, A - I).arrow_forward
