Question

(a) In eukaryotic cells, repressor proteins attached to a region of DNA called __________________. (b) Briefly describe what effect repressor proteins have on the process of transcription. (c) Consider the following partial single-stranded DNA sequence: T A C G G T A C A G C C T C G If the above DNA sequence is transcribed and translated, what would the mRNA and amino acid sequences be? mRNA: Amino Acids: (d) Suppose that nucleotides #4-5 and #13-14 were spliced out of the above mRNA sequence. In the space below, write the mRNA sequence that would remain after this splicing occurred: (e) What amino acid sequence would a cell produce using the sequence you wrote in part b? (f) Go back to the original mRNA sequence you wrote in part a. Now suppose that nucleotides #7-9 were spliced out of this molecule. In the space below, write the mRNA sequence that would remain after this splicing occurred: (g) What amino acid sequence would a cell producing using the sequence you wrote in part d? (h) Is it possible the same gene to produce more than one type of protein? Explain your answer.
