The instructions for making proteins are coded in the

messenger RNA /mRNA!

Explanation:

mRNA is a type of RNA that carries the information about the type of protein to be made

It carries it to the ribosomes for the production of proteins

Ribosomes decode the information on the ribosome and make protein from the amino acid sequence directed by the mRNA

The mRNA or messenger RNA contains information for protein coding.

The messenger RNA or mRNA conveys the directions for making proteins. Like DNA, proteins are polymers: long chains amassed from prefab subatomic units, which, on account of proteins, are amino acids. An enormous sub-atomic machine called the ribosome interprets the mRNA code and collects the proteins.  

Ribosomes read the message in mRNA in three letter "words" called codon, which mean explicit amino acids or a guidance to quit making the protein. Every conceivable three letter course of action of A, C, U, G (e.g., AAA, AAU, GGC, and so on) is a particular guidance and the correspondence of these directions and the amino acids is known as the "hereditary code".

then that particular organisms become extinct.
