The 'one gene one enzyme' concept means:

Nirenberg synthesized an $m-RNA$ containing $34$ poly-adenine and found a $11$ poly-lysine polypeptide structure. This proves that the genetic code for lysine is ......

Which of the following statements regarding the genetic code is incorrect?
$i.$ The codon is a triplet.
$ii.$ $64$ codons code for amino acids.
$iii.$ The genetic code is unambiguous.
$iv.$ The genetic code is universal.
$v.$ $AUG$ has dual functions.

$A$ mature $mRNA$ consists of $900$ bases without any stop codon in between. Calculate the number of amino acids coded by this $mRNA$ during translation.

The cell-free system was helpful in which of the following?

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.
