Less complex organisms require additional sets of the genetic code.

|
|
The nucleotide sequence of the genetic code is exact same for every organism.
|
|
|
The genetic code for every living organism is made from the same component.
|
|
|
Some simple organiosms do not have genetic code.

Detailed explanation-1: -The genetic code is used to store protein blueprints in DNA written in an alphabet of bases in the form of triplets called codons. The blueprint for a protein is transcribed to messenger RNA.
Detailed explanation-2: -So the correct option is ‘there are 64 triple codons and only 20 amino adds’.
Detailed explanation-3: -DNA. Genes consist of deoxyribonucleic acid (DNA). DNA contains the code, or blueprint, used to synthesize a protein. Genes vary in size, depending on the sizes of the proteins for which they code.
Detailed explanation-4: -The genetic code is a set of instructions that direct the translation of DNA into 20 amino acids, the basic units of proteins in living cells. The genetic code is made up of codons, which are three-letter chains of nucleotides. Each codon codes for one specific amino acid.
