Practice Problem 25.11
(a) Using the first codon given for each amino acid in Table 25.2, write the base sequence of mRNA that would translate the synthesis of the following pentapeptide:
Arg · Ile · Cys · Tyr · Val
(b) What base sequence in the DNA sense strand would correspond with this mRNA?
(c) What anticodons would appear in the tRNAs involved in the pentapeptide synthesis?
