The codon $CUA$ $CUA$ $CUA$ codes for which of the following amino acids?

Define the following terms:
$1.$ Genetic code
$2.$ Degenerate codons

Initiation codon of protein synthesis (in eukaryotes) is

For the genetic code,choose the correct option for the given statements. Where $T$ stands for True and $F$ stands for False.
$(1)$ Phenylalanine $(Phe)$ amino acid is coded by more than three codons.
$(2)$ The codon is read in $t-RNA$ in a contiguous fashion.
$(3)$ $UUC$ would code for phenylalanine.
$(4)$ $AUG$ codes for Methionine.

What is indicated by $AUG$?
