Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which do ALL proteins have?
A
beta pleated sheets
B
globular shape
C
primary structure
D
quaternary structure
Explanation: 

Detailed explanation-1: -To reiterate, the primary structure of a protein is defined as the sequence of amino acids linked together to form a polypeptide chain. Each amino acid is linked to the next amino acid through peptide bonds created during the protein biosynthesis process.

Detailed explanation-2: -The primary structure of a peptide or protein is the linear sequence of its amino acids (AAs). By convention, the primary structure of a protein is read and written from the amino-terminal (N) to the carboxyl-terminal (C) end. Each amino acid is connected to the next by a peptide bond.

Detailed explanation-3: -The Primary structure of proteins is the exact ordering of amino acids forming their chains. The exact sequence of the proteins is very important as it determines the final fold and therefore the function of the protein. The number of polypeptide chains together form proteins.

Detailed explanation-4: -The answer is No. Not all proteins molecule have primary, secondary, tertiary, and quaternary structures. Not all protein molecules have a quaternary structure. The tertiary structure of protein describes the 3-D structure and shape of the protein.

Detailed explanation-5: -Proteins have a primary structure.
