The genetic code is sets of rules by which information encoded in genetic material is translated into amino acid .so the genetic code consist of total 64 codons . Three of Which do not code for amino acid but indicate the end of protein.
So genetic code consist of 64,3-base codons
Option (A) is correct.

The genetic code is read in groups of three (3) nucleotides called codons. Some mutations are silent because they have no effect on the phenotype. How is that possible? Since there was a mutation in one of the codons, that gene will not be expressed. o It is not possible, mutations are always expressed and always have an effect The mutation changed the codon but the new codon codes for the same amino acid The ribosome knows there was a...

The genetic code is considered degenerate because most amino acids are encoded by at least two different codons. Some researchers have hypothesized that during evolution the genetic code has been optimized for its intended use in different organisms. Reseachers can study this by examining the relationship between the frequency with which an amino acid appears in all the proteins in an organism and the total number of codons for an amino acid. An optimized organism would use amino acids in...

37. After looking at the genetic code table, you can tell that the degeneracy (or redundancy) in the genetic code is best illustrated by: A) stop codons. B) threonine (thr) codons. C) tryptophan (trp) codons. D) methionine (met) codons. E) operator sequences. 38. The phenomenon in D. melanogaster known as Position-Effect Variegation (PEV) provides powerful evidence that: A) DNA is the genetic material.
