Question
The sequence is: TACAAACGCTTGTGCCGCAGGTGCTATACAATCChange either the first of second base of any triplet in this sequence other than the start or stop codon and write the nucleic acid sequence from transcription?
What happens to the amino acid sequence in translation?
Thanks a bunch!
Explanation / Answer
DNA = TAC---AAA-CGC-TTG-TGC-CGC-AGG-TGC-TAT-ACA---ATC RNA = AUG---UUU-GCG-AAC-ACG-GCG-UCC-ACG-AUA-UGU---UAG 1 2 3 4 5 6 7 8 9 10 11 AA = START---phe-ala-asn-thr-ala-ser-thr-ile-cys---STOP Suppose we change the second base of the 7th triplet from G to A. It becomes AAG -> UUC or "phe" instead of AGG -> UCC or "ser". The sequence becomes: DNA = TAC---AAA-CGC-TTG-TGC-CGC-AAG-TGC-TAT-ACA---ATC RNA = AUG---UUU-GCG-AAC-ACG-GCG-UUC-ACG-AUA-UGU---UAG 1 2 3 4 5 6 7 8 9 10 11 AA = START---phe-ala-asn-thr-ala-phe-thr-ile-cys---STOP
