Answer:In a cell, proteins are made in the cell's ribosomes. Ribosomes string together long chains of amino acids to synthesize proteins. The mRNA (messenger ribonucleic acid), tRNA (transfer ribonucleic acid) and the amino acids work together to form proteins.
Explanation: Proteins are large biomolecules, or macromolecules, consisting of one or more long chains of amino acid residues. Proteins perform a vast array of functions within organisms, including catalysing metabolic reactions, DNA replication, responding to stimuli, providing structure to cells, and organisms, 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.
