Answer: -long chains of nucleic acid
What are polypeptides?

A polypeptide is a string or linear chain of amino acids linked together. Amino acids are the basic building blocks of proteins. A single polypeptide chain might make up the entire primary structure of a simple protein; more complex proteins are formed when two or more polypeptides link together. Each protein is a polymer of amino acids.

Peptides (from Greek language πεπτός peptós "digested"; derived from πέσσειν péssein "to digest") are short chains of between two and fifty amino acids linked by peptide bonds. Chains of fewer than ten or fifteen amino acids are called oligopeptides and include dipeptides tripeptides and tetrapeptides. A polypeptide is a longer continuous unbranched peptide chain of up to approximately fifty amino acids. Hence peptides fall under the broad chemical classes of biological polymers and oligomers alongside nu…

Despite multiple research articles on polypeptide antibiotics the understanding of their exact mechanism of action and the extent of their toxicity and effe...
