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: -This process is called protein synthesis, and it actually consists of two processes-transcription and translation . In eukaryotic cells, transcription takes place in the nucleus . During transcription, DNA is used as a template to make a molecule of messenger RNA ( mRNA ).
Detailed explanation-3: -A peptide bond, also called an eupeptide bond, is a chemical bond that is formed by joining the carboxyl group of one amino acid to the amino group of another.
