Q. What is not true for the genetic code?

NTA AbhyasNTA Abhyas 2022

Solution:

The genetic code is universal, for example, from bacteria to human UUU would code for phenylalanine (phe). Some exceptions to this rule have been found in mitochondrial codons, and in some protozoans. The genetic code shows degenerecy, some of the amino acids are coded by more than one codon. One codon codes for only one amino acid, hence, it is unambiguous, specific and the codon is read in mRNA in a contiguous fashion. There are no punctuations.
