Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The amino acid sequence of a polypeptide chain comprises the ____ structure of the protein.
A
Primary
B
Secondary
C
Tertiary
D
Quaternary
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: -Primary structure. The simplest level of protein structure, primary structure, is simply the sequence of amino acids in a polypeptide chain.

Detailed explanation-3: -The linear sequence of amino acids within a protein is considered the primary structure of the protein. Proteins are built from a set of only twenty amino acids, each of which has a unique side chain.

Detailed explanation-4: -The primary structure of a protein or polypeptide is the actual sequence of its amino acids. Primary structure is determined by the order of the deoxyribonucleotide bases in genes.
