Question

Molecular Genetics, Assignment for Chapter 2 A table showing all of the 64 codons and the amino acid for which they code can be found in your book. Below is a Prokaryotic DNA sequence with the corresponding protein sequence for each of the three forward reading frames. Note that in this case, Z, represents one of the three translational termination codons. In prokaryotes, transcription starts at promoters that are most closely related to a-10 region of TATAAT and a compatable-35 region. Transcription terminates at stem-loop structures that can form in inverted repeat regions. Translation starts at AUG codons corresponding to the amino acid M. Adjacent to the starting AUG, 8-10 bases upstream (i.e, to the left), you will find a ribosomal binding site AGGAGG which is complementary to the 3 end of the 16S rRNA. Find the transcription start site, TATAAT, and circle it. Find the ribosomal binding site and draw a box around it. 3. Find the adjacent AUG and record the protein sequence below, adjacent to the word "Protein 4. Amutation at base 115 converts the C at this position to an A. Write the protein sequence for the 5. Record the protein sequence that would be made when a C is deleted at position 120 next to the 6. 7. What impact would a T>G substitution have at position 40 of the original sequence? mutant next to the "115 C A" line below. "120 Delete C" line.
