The sequence of amino acids in a protein can offer insights into its three-dimensional structure and its function, cellular location, and evolution. Most of these insights are derived by searching for similarities with other known sequences.
Q. What does each amino acid sequence eventually create?
When connected together by a series of peptide bonds, amino acids form a polypeptide, another word for protein. The polypeptide will then fold into a specific conformation depending on the interactions (dashed lines) between its amino acid side chains.

Q. What is the amino acid sequence produced?
Each group of three bases in mRNA constitutes a codon, and each codon specifies a particular amino acid (hence, it is a triplet code). The mRNA sequence is thus used as a template to assemble—in order—the chain of amino acids that form a protein.
Q. Does the order of amino acids matter?
The amino acids contain R groups that interact with each other creating a three – dimensional structure. This higher – order structure decides the biological activity of that protein. if the wrong amino acid joins the polypeptide chain the higher – order structure will change, effecting the functioning of the protein.
Q. Is the order of amino acids in a protein important?
Peptide Bonds The sequence and the number of amino acids ultimately determine the protein’s shape, size, and function. Each amino acid is attached to another amino acid by a covalent bond, known as a peptide bond.
Q. What is the sequence of amino acids in a polypeptide?
A series of amino acids joined by peptide bonds form a polypeptide chain, and each amino acid unit in a polypeptide is called a residue.
Q. How is a protein formed from amino acids?
Proteins are formed in a condensation reaction when amino acid molecules join together and a water molecule is removed. The new bond formed in protein molecules where amino acids have joined (-CONH) is called an amide link or a peptide link.
