Question text Consider the following DNA template strand sequence: 3' - TACGGACTTACG - 5' Using this DNA sequence, answer the following: a. Identify the mRNA sequence transcribed from this DNA template. Answer 1 Question 21[select: , 5' - AUG CCU GAA UGC - 3', 5' - AUG CCG UUU ACG - 3', 5' - UAC GGA CUU ACG - 3', 5' - UAC GGC UUU ACG - 3'] b. Determine the amino acid sequence that corresponds to the mRNA sequence. Answer 2 Question 21[select: , Met-Pro-Glu-Cys, Tyr-Gly-Leu-Thr, Tyr-Gly-Leu-Arg] c. If a mutation changes the DNA sequence to 3' - TACGGCCTTACG - 5', identify the new mRNA sequence and amino acid sequence. New mRNA sequence: Answer 3 Question 21[select: , AUG CCG GAA UGC, 5' - AUG CCG UUU ACG - 3', 5' - UAC GGC UUU ACG - 3', 5' - UAC GGC UUU TGC - 3'] New amino acid sequence: Answer 4 Question 21[select: , Met-Pro-Phe-Thr, Tyr-Gly-Phe-Thr, Tyr-Gly-Phe-Cys] d. Determine if the protein resulting from the mutated DNA will be functional or non-functional based on the change. Answer 5 Question 21[select: , Functional, Non-functional] (I:5)

To approach this problem, I’ll walk through each subpart and evaluate every choice before identifying the logical pattern that leads to the correct conclusions. Part a: Identify the mRNA sequence transcribed from the DNA template 3' - TACGGACTTACG - 5'. - Option 1: 5' - AUG CCU GAA UGC - 3'. This matches the RNA sequence produced by complementing the template strand (A pairs with T, U replaces T in RNA, C with G, etc.) and placing it in 5' to 3' orientation. Specifically, TACG GACTT ACG (template) yields A U G C C U G A A U G C in 5'→3', which aligns with this option. This is a correct transcription outcome. - Option 2: 5' - AUG CCG UUU ACG - 3'. Here, the codon sequence includes UUU, which would encode phenylalanine, but the template does not support this codon arrangement after transcription, so this is inconsistent with the g......Login to view full explanation

Question32 Which one of the following statements describes a key difference between transcription as it occurs in bacteria compared to eukaryotes? Select one alternative: Bacterial translation can start before transcription of the same gene has finished. Bacteria use three distinct RNA polymerases that synthesise different RNA types. In bacteria, synthesis of the RNA chain occurs in the 5′ → 3′ direction. Promoter regions are only found in bacterial operons. ResetMaximum marks: 1 Flag question undefined
