Differentiate between the genetic codes given below:
Unambiguous and Universal
When one codon codes for only one amino acid,it is called Unambiguous and specific genetic codes. When the genetic code is valid for all organisms, it is said to be universal.
Example: from bacteria to human UUU would code for Phenylalanine (Phe). Some exception to this rule have been found in mitochondrial codons and in some protozoans.
