Question

The sequence in which amino acids are arranged in a protein is called______

• A. primary structure
• B. secondary structure
• C. tertiary structure
• D. tetrahedral structure

Answer 1

Answer: (A)

primary structure

The sequence in which amino acids are arranged in a protein is called primary structure.

The linear sequence of amino acids constitutes a protein's primary structure. The sequence is written from the amino-terminal end (the first amino acid) to the carboxyl-terminal end.

All properties of a protein are derived from the primary structure, the linear sequence.

Option A is correct.
