The following DNA sequence occurs in the nontemplate strand of a gene in a bacterium (the promoter sequence is located to the left but is not shown): 5′-GAATGTCAGAACTGCCATGCTTCATATGAATAGACCTCTAG-3′

(a) What is the ribonucleotide sequence of the mRNA molecule that is transcribed from this piece of DNA?

(b) What is the amino acid sequence of the polypeptide encoded by this mRNA? 

(c) If the nucleotide indicated by the arrow undergoes a mutation that changes T to A, what will be the resulting amino acid sequence following transcription and translation?
