a. Write the template DNA (complementary strand) sequence for the wild type gene above
b. Write the DNA sequence of the mutant gene (Both DNA strands)
c. Write the sequence of mRNA produced from the mutant gene
d. Write the sequence of the mutant protein using the codon usage table provided in the end of this document.
Consider the following DNA template:
