We know there are 4 nucleotides in DNA. Out of 4 , when 3 nucleotides are set together , it is called codon. For example CYTOCINE, ADENINE, GUANINE (CAG) is a codon that refers to glutamine , a amino acid.
Actualy , three nucleotides determine the amino acid. It is known as specific genetic code. It means only these three nucleotide (codon) specifies only one amino acid.
The position of the nucleotides also determine the amino acid. For example CAG produce glutamine while CGA produces the alanine. This is the order of a genetic code.
Sometimes more than one codon can specify each amino acid . For example took proline. It is represented by CCU, CCC. Here two codon specify a amino acid.
Genetic code is always triplatic. It means presence of three nucleotides to denotes a codon.
So the accurate answer is Degenerate or redundant genetic code.

In the process of translation, mRNA attaches to ribosomes DNA is replicated proteins are synthesized RNA is synthesized QUESTION 11 What does it mean when we say the genetic code is unambiguous? More than one codon can specify the addition of the same amino acid. The genetic code is different for different domains of organisms. Each codon can specify the addition of only one amino acid. The genetic code is universal (the same for all organisms).

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...
