What is not true for genetic code?
A
It is nearly universal.
B
It is degenerate.
C
It is unambiguous.
D
A codon in $mRNA$ is read in a non contiguous fashion.
(AIPMT-2009)
Solution
(d) : The relationship between the sequence of amino acids in a polypeptide and nucleotide sequence of $DNA $ or $mRNA$ is called genetic code. The genetic code is continuous and does not possess pause after the triplets. So a codon in $mRNA$ is a noncontiguous fashion. If a nucleotide is deleted or added, the whole genetic code will read differently.
