Textbook Question
Chapter 12, Problem 15PDQ
Shown here is a theoretical viral mRNA sequence
5'-AUGCAUACCUAUGAGACCCUUGGA-3'
(a) Assuming that it could arise from overlapping genes, how many different polypeptide sequences can be produced? Using the chart in Figure 12–7, what are the sequences?
(b) A base-substitution mutation that altered the sequence in part (a) eliminated the synthesis of all but one polypeptide. The altered sequence is shown below. Use Figure 12–7 to determine why it was altered.

Consider the following DNA sequence, which codes for a short polypeptide:
5'-ATGGGCTTAGCGTAGGTTAGT-3'
Determine the mRNA transcript of this sequence. You have to write these sequences from the 5' end to the 3' end and indicate those ends as shown in the original sequence in order to get the full mark.
How many amino acids will make up this polypeptide?
Determine the first four anticodons that will be used in order to translate this sequence.
Given the partial transposons DNA sequence 5’-ACCGTATTCGGT-3’ upstream from the central region, assuming both terminal inverted repeats and flanking direct repeats have 6 base pairs, hypothetically write the transposon structure downstream from the central region.
Refer to the DNA sequence provided:
3’ -TACTGAAGCGGCAGCCCCGCATGAGTAGACCTTACT-5’
a. What is the mRNA transcript of the anticoding strand of the DNA model?
b. What is the amino acid sequence of the polypeptide chain that will be translated from the mRNA in (a)?

- in the human gene for the beta chain of hemoglobin, the first 30 nucleotides in the amino acid coding region is represented by the sequence 3'TACCACGTGGACTGAGGACTCCTCTTCAGA-5'. What is the sequence of the partner strand? If the DNA duplex for the beta chain of hemoglobin above were transcribed from left to right, deduce the base sequence of the RNA in this coding region.arrow_forwardThe flu virus maximizes the use of its limited (13.5 kb) genome by using alternative translation initiation sites, overlapping reading frames, and ribosomal frameshifting. For example, part of the viral PA gene includes a rarely used CGU codon. When the ribosome pauses to translate this codon, it may slip ahead by one nucleotide and produce a polypeptide with a diff erent C-terminal sequence. From the partial mRNA sequence shown here, determine the normal polypeptide sequence and the sequence with the frameshift.arrow_forwardConsider the following coding 71 nucleotide DNA template sequence (It does not contain a translational start): 5’- GTTTCCCCTATGCTTCATCACGAGGGCACTGACATGTGTAAACGAAATTCCAACCTGAGCGGCGT GTTGAG-3’ By in vitro translating the mRNA, you determined that the translated peptide is 15 amino acids long.

- The DNA-binding domain of each CREB protein subunit recognizes the sequence 5′–TGACGTCA–3′. Due to random chance, how often would you expect this sequence to occur in the human genome, which contains approximately 3 billion base pairs? Actually, only a few doze genes are activated by the CREB protein. Does the value of a few dozen agree with the number of random occurrences expected in the human genome? If the number of random occurrences of the sequence in the human genome is much higher than a few dozen, provide at least one explanation why the CREB protein is not activating more than a few dozen gene Actually, only a few doze genes are activated by the CREB protein.
