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-2: -The fundamental reaction of protein synthesis is the formation of a peptide bond between the carboxyl group at the end of a growing polypeptide chain and a free amino group on an incoming amino acid. Consequently, a protein is synthesized stepwise from its N-terminal end to its C-terminal end.
Detailed explanation-3: -To build proteins, cells use a complex assembly of molecules called a ribosome. The ribosome assembles amino acids into the proper order and links them together via peptide bonds. This process, known as translation, creates a long string of amino acids called a polypeptide chain.
Detailed explanation-4: -The ribosomes read the messenger RNA to produce a chain of amino acids?. Each amino acid is delivered to the ribosome by a transfer RNA? molecule depending on the code in the messenger RNA. These amino acids are added in sequence to form a chain of amino acids.
