During protein synthesis in an organism, at one point the process comes to a halt. Select the group of the three codons from the following, from which anyone of the three could bring about this halt.
$UUU, \,UCC, \,UAU$
$UUC,\, UUA,\, UAC$
$UAG, \,UGA,\, UAA$
$UUG,\, UCA, \,UCG$
State the salient features of genetic code.
A triplet codon means
$A$ : Triplet genetic code can be confirmed by frame shift mutations.
$R$ : Frame shifting involves the change in protein product coded by triplet codons
Genetic code determines
Out of $64$ codons, $61$ codons code for $20$ types of amino acid. It is called
