MCQ
What is not true for genetic code?
- AIt is nearly universal.
- BIt is degenerate.
- CIt is unambiguous.
- ✓A codon in $mRNA$ is read in a non contiguous fashion.
✓
Answer
Correct option: D.
A codon in $mRNA$ is read in a non contiguous fashion.
d
(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.
