Which component of dna makes up the language of genetic code?
loris [4]

Answer:

nitrogenous bases (adenine, guanine, thymine, uracil, cytosine) which are part of the nucleotides

Explanation:

The genetic code is the set of rules within genetic material that carries information about products that have to be synthesized (usually proteins).

During the process of translation (protein synthesis) code in mRNA (formed during the transcription of DNA) is read thanks to ribosome and tRNA. Transfer RNA (tRNA) molecules carry amino acids (for protein formation) and read the mRNA three nucleotides at a time and that happens within the ribosome. Those nucleotide triplets on mRNA are called codons and they specify which amino acid will be added next during protein synthesis.  

The genetic code is expressed in a simple table with 64 entries.
