Question

The fourth sequence shown above has two mutational differences from the first sequence. Specifically, the third codon is ttg versus ctc in the first sequence. These two codons are two mutational steps away from each other. Supposing that the ctc sequence gave rise to the ttg sequence, do you think it is more

Answer 1

. The eight amino acids for each of the five sequences are:ATG TCT CTC ACC AAC AAG AAC GTCMet Ser Leu Thr Asn Lys Asn ValATG gCT CTC ACC AAC AAG AAC GTCMet Ala Leu Thr Asn Lys Asn ValATG TCg CTC ACC AAC AAG AAC GTCMet Ser Leu Thr Asn Lys Asn ValATG TCT tTg ACC AAC AAG AAC GTCMet Ser Leu Thr Asn Lys Asn ValATG TCT CTC ACC AAC AAG AAC GTgMet Ser Leu Thr Asn Lys Asn Val© 2017 Sinauer Associates, Inc.
