Options
- A(A)-(IV), (B)-(III), (C)-(II), (D)-(I)
- B(A)-(III), (B)-(IV), (C)-(II), (D)-(I)
- C(A)-(III), (B)-(IV), (C)-(I), (D)-(II)
- D(A)-(IV), (B)-(III), (C)-(I), (D)-(II)
Correct answer
B. (A)-(III), (B)-(IV), (C)-(II), (D)-(I)
Step-by-step solution
Primary structure of proteins refers to the specific sequence of amino acids connected by peptide bonds (A)-(III). Secondary structure refers to the local folding of the polypeptide chain, such as -helix and -pleated sheet, which are stabilized by hydrogen bonds (B)-(IV). Phosphodiester linkage connects the 3' -carbon of the pentose sugar of one nucleotide to the 5' -carbon of the pentose sugar of the next nucleotide (C)-(II). N-glycosidic linkage connects the 1' -carbon of the pentose sugar to the nitrogenous base
