Biology Question on the molecular basis of inheritance
What is not true for genetic code ?
A
It is nearly universal
B
A codon in m-RNA is read in a non-contiguous fashion
C
It is unambiguous
D
It is degenerate
Answer
A codon in m-RNA is read in a non-contiguous fashion
Explanation
Solution
The relationship between the sequence of amino acids in a polypeptide and nucleotide sequence of DNA or wRNA is called genetic code. The genetic code is continuous and does not possess pause after the triplets. So a codon in RNA is a non-contiguous fashion. If a nucleotide is deleted or added, the whole genetic code will read differently.
