What polypeptide would be synthesized from the following template strand of DNA: CGG TGT CTT TTA? Analysis To determine what polypeptide is synthesized from a DNA template, two steps are needed. First use the DNA sequence to determine the transcribed mRNA sequence: C pairs with G, T pairs with A, and A (on DNA) pairs with U (on mRNA). Then use the codons in Table 17.3 to determine what amino acids are coded for by a given codon in mRNA.

What polypeptide would be synthesized from the following template strand of DNA:
CGG TGT CTT TTA?
Analysis
To determine what polypeptide is synthesized from a DNA template, two steps are needed. First use the DNA sequence to determine the transcribed mRNA sequence: C pairs with G, T pairs with A, and A (on DNA) pairs with U (on mRNA). Then use the codons in Table 17.3 to determine what amino acids are coded for by a given codon in mRNA.
