Question

polypeptide chain sequence

Answer 1

[AI-generated answer — Bot GPT 3.5]

A polypeptide chain is a linear sequence of amino acid residues linked together by peptide bonds. The sequence is determined by the sequence of nucleotides in the corresponding gene, which is then translated into an amino acid sequence during protein synthesis.

The sequence of a polypeptide chain is typically represented using the one-letter amino acid code, where each amino acid is abbreviated with a single letter. For example, the sequence of a chain could be represented as "IGVETCAK".

The sequence of a polypeptide chain is important because it determines the structure and function of the protein. The specific arrangement of amino acids in the chain determines how the protein will fold into its three-dimensional structure, which in turn determines its function in the body. Any changes or mutations in the sequence can lead to alterations in protein structure and function, potentially causing genetic diseases or other disorders.
