Exercise 2

Predict the effects of the following mutations on phage R17 coat gene and replicase gene translation:
a. An amber mutation (premature stop codon) six codons downstream of the coat gene initiation codon.
b. Mutations in the stem loop around the coat gene initiation codon that weaken the base-pairing in the stem loop.
c. Mutations in the interior of the replicase gene that cause it to base-pair with the coat gene initiation codon.
