Question

You are given the following DNA sequence and have determined that it is the sense parental strand. ATTGCCATGAAACGCCCCGGTACACCATTGTTCGGCAAATAAAAATAA What is the polypeptide sequence of this sense strand? Use the three letter abbreviation and separate the amino acids with a dash - e.g. Trp-Thr-Ala. If there is a stop codon - you may add an asterisk to the sequence - e.g. Trp-Thr-Ala-*

Answer 1

* (Stop) - Arg - Cys - Phe - Ala - Gly - Pro - Cys - Gly - Asn - Lys - Pro - Phe - Ile - Phe - Ile

Step-by-step explanation:

This question involves gene expression, which consists of transcription and translation. The process of transcription involves synthesis of mRNA from DNA template as follows:

DNA - mRNA

ATT - UAA

GCC - CGG

ATG - UAC

AAA - UUU

CGC - GCG

CCC - GGG

GGT - CCA

ACA - UGU

CCA - GGU

TTG - AAC

TTC - AAG

GGC - CCG

AAA - UUU

TAA - AUU

AAA - UUU

TAA - AUU

Using the codon chart, each mRNA codon is translated into an amino acid as follows:

* (Stop) - Arg - Cys - Phe - Ala - Gly - Pro - Cys - Gly - Asn - Lys - Pro - Phe - Ile - Phe - Ile
