Assertion :- UGG is a chain termination codon.
Reason : It does not code any amino acid.

Assertion (A): Some codons act as terminating or stop codons. Reason ( R): 3 codons do not code for any amino acids.

The following codon do not code for any amino acid are

The following codon do not code for any amino acid are

The number of stop codons which do not code for any amino acid is

Assertion: Amber codon is a terminating codon. Reason: If in a mRNA, a termination codon is present, the protein synthesis stops abruptly whether the protein synthesis is complete or not.

The number of stop codons which do not code for any amino acid is :

The codons causing chain termination are

The codons causing chain termination (stop codons) are
