DNA translation and Protein Synthesis
1. For the following strands of DNA write out the corresponding mRNA
2. For the parent strand of DNA listed below write out the mRNA strand and
then the polypeptide (protein chain) encoded by the strand. (Once you
have transcribed the strand – look for the start codon, start there and
continue until there is a stop codon)
3. For the following RNA strand – write the corresponding DNA that would
have served as a template for it.
4. Part of the amino acid sequence of the A chain of insulin is "glutaminecysteine-cysteine-alanine". Use the genetic code chart (Figure 17.4) to decide
which of the following DNA strands could encode this tetrapeptide.
