The assumption that the genetic code is a triplet was suggested by:

The number of codons effective in coding twenty amino acids is:

$A$ naturally occurring coding strand composed of alternating $C$ and $U$ residues would result in the formation of

How many amino acids are encoded by only a single codon?

Which one of the following is true?

$(i)$ The codon is read in mRNA in a contiguous fashion. There are no punctuations.
(ii) Some amino acids are coded by more than one codon.
(iii) $UUU$ would code for phenylalanine.
(iv) $GAA$ is a stop terminator codon.
Comparing the above statements (i-iv),select the correct option marked with $T$ (True) and $F$ (False) with respect to the salient features of the genetic code.
