Which of the following statements are correct ?
(A) A tripeptide had two peptide bonds.
(B) A penapeptide contains five amino acids.
(C ) Nucleotide is a product of base and sugar
(D) In cellulose, `beta`-glycosidic linkages are present.

Options

A. B, C, D
B. C, D only
C. A, B, D
D. A, C only

Answer

C

Explanation

The explanations of given statements are as follows :
(A) A tripetide contains 3 amino acids a linked by two peptide linkages. Thus, statement (A) is correct.
(B) A pentapeptide contains five amino acids linked by four peptide linkages. Thus, statement (B) is also correct.
(C ) In cellulose, `beta` - D glucose units are joined by glycosidic linkage between C - 1 of , one glucose and C-4 of the next glucose unit. Thus, statement (D) is a also correct.
Hence, option (c ) is correct.
