Explanation:

Proteins are large bio-molecules consisting  of  one  or  more  long  chains  of  amino  acid residues.
Proteins are assembled from amino acids using information encoded in genes. Each protein has its own unique amino acid sequence that is specified by the nucleotide sequence of the gene encoding this protein.
Learning: Proteins perform a vast array of functions within organisms, including catalysing metabolic reactions, DNA replication, responding to stimuli, and transporting molecules from one location to another.

Proteins differ from one another primarily in their sequence of amino acids, which is dictated by the nucleotide sequence of their genes, and which usually results in protein folding into a specific three- dimensional structure that determines its activity.
The process of synthesizing a protein from an mRNA template is known as translation
