Question
Biology Question on the molecular basis of inheritance
Initiation codon of protein synthesis (in eukaryotes) is
A
GUA
B
GCA
C
CCA
D
AUG
Answer
AUG
Explanation
Solution
AUG codes for methionine and is initiation or start codon which starts the synthesis of polypeptide. UAA (ochre), UAG (amber) and UGA (opal) do not specify any amino acid so they are called termination codons. CUU, CUC, CUA and CUG codes for leucine whereas GCU, GCC, GCA and GCG codes for alanine.
