|
|
The genetic code is overlapping
|
|
|
The genetic code is universal
|
|
|
Degenerate codons specify the same amino acids
|
|
|
The genetic code is a triplet
|
Detailed explanation-1: -It is also important to note that the genetic code does not overlap, meaning that each nucleotide is part of only one codon-a single nucleotide cannot be part of two adjacent codons. Furthermore, the genetic code is nearly universal, with only rare variations reported.
Detailed explanation-2: -Hence, Option (b) i.e. A codon in mRNA is read in a non-contiguous fashion is the correct answer as it is not a true statement for genetic code. Note: Each codon is made of three nitrogenous bases, do not overlap other codons and are independent. Codons in mRNA are read in continuous or contiguous fashion.
Detailed explanation-3: -It is triplet, universal, ambiguous and degenerate.
Detailed explanation-4: -So, the correct answer is ‘A codon in mRNA is read in a non-contiguous fashion’.
