Select the correct option for George Gamow.

$A$ sequence of how many nucleotides in messenger $RNA$ makes a codon for an amino acid?

$A$ strand of deoxyribonucleotide contains information for a polypeptide consisting of $50$ amino acids. If a mutation occurs at the $25$th codon,changing $UAU$ to $UAA$,what will be the result?

Select the incorrect statement$(s)$.
$i.$ Six codons do not code for any amino acid.
$ii.$ Codon is read in $mRNA$ in a contiguous fashion.
$iii.$ Three codons function as stop codons.
$iv.$ The initiation codon $AUG$ codes for methionine.

Identify the amino acid sequence coded by the given $mRNA$ sequence: $5'-AUG-UUU-UUC-GUG-AUA-UGG-3'$
