Shown below are three genes (gene 1, gene 2, and gene 3) located on the same bacterial chromosome. a) Indicate where on the diagram you would find the following for each gene: Promoter (p1 for gene 1, p2 for gene 2, and p3 for gene 3) Transcription termination site (tts1, tts2, and tts3) Start codon (start1, start2, and start3) Stop codon (stop1, stop2, and stop3) Template strand (ts1, ts2, and ts3), the DNA strand that directs RNA synthesis Be sure to indicate the component on the appropriate molecule (DNA or RNA).
Consider the Rho-dependent terminator sequence 5’CCCAGCCCGCCUAAUGAGCGGCCUUUUUUUU-3’. What affect would a point mutation at any one of the bolded and underlined nucleotides disrupt termination of transcription? Group of answer choices 1.Mutation in one of these nucleotides would disrupt base pairing, but not affect the formation of the hairpin and termination proceeds. 2.Mutation in one of these nucleotides would have no affect on base pairing, so the termination hairpin is formed and termination proceeds. 3.Mutation in one of these nucleotides would not disrupt base pairing, but would prevent the formation of the hairpin and disrupt termination. 4.Mutation in one of these nucleotides would disrupt base pairing, preventing the formation of the hairpin and disrupting termination.

Transcription factors function in the nucleus. However, like (almost) all eukaryotic proteins,they are translated in the cytosol. Can you draw a visual to explain how transcription factor proteinsenter the nucleus from the cytoplasm? Can you also include a representation of relevant proteins and proteindomains to explain how these proteins reach their destination. Thank you
