A(n) <u>gene</u> is a sequence of organic nitrogen base pairs that codes for a polypeptide or a protein.
What is polypeptide?
Peptides are made up of short chains of amino acids joined together by peptide bonds. The word "peptide" comes from the Ancient Greek word "peptós," which means "digested." Oligopeptides, which comprise dipeptides, tripeptides, and tetrapeptides, are chains of fewer than twenty amino acids.
A polypeptide is a peptide chain that is longer, continuous, and unbranched.
Therefore, along with nucleic acids, oligosaccharides, polysaccharides, and others, peptides belong to the large chemical families of biological polymers and oligomers.
A protein is a polypeptide that has more than 50 amino acids, on average. A protein is made up of one or more polypeptides that are structured in a biologically useful manner. Proteins are frequently coupled to other proteins, other macromolecules like DNA or RNA, or complex macromolecular assemblies.
