Detailed explanation-1: -A protein molecule is made from a long chain of these amino acids, each linked to its neighbor through a covalent peptide bond (Figure 3-1). Proteins are therefore also known as polypeptides. Each type of protein has a unique sequence of amino acids, exactly the same from one molecule to the next.

Detailed explanation-3: -X is often used to highlight the presence of an unknown amino acid. It may happen due to multiple sequences showing different amino acids or if the original sequence’s quality was too poor to attribute a nucleotide with certainty.

Detailed explanation-4: -A protein consists of one or more chains of amino acids (called polypeptides) whose sequence is encoded in a gene.
