Both human DNA and RNA are chiral molecules. The chirality in DNA and RNA arises due to the presence of

$$ \text { Match List - I with List - II. } $$

Choose the correct answer from the options given below :

Given below are two statements :

Statement I : Sucrose is dextrorotatory. However, sucrose upon hydrolysis gives a solution having mixture of products. This solution shows laevorotation.

Statement II : Hydrolysis of sucrose gives glucose and fructose. Since the laevorotation of glucose is more than the dextrorotation of fructose, the resulting solution becomes laevorotatory.

In the light of the above statements, choose the correct answer from the options given below :

The correct statements are :

A. Activation energy for enzyme catalysed hydrolysis of sucrose is lower than that of acid catalysed hydrolysis.

B. During denaturation, secondary and tertiary structures of a protein are destroyed but primary structure remains intact.

C. Nucleotides are joined together by glycosidic linkage between $\mathrm{C}_1$ and $\mathrm{C}_4$ carbons of the pentose sugar.

D. Quaternary structure of proteins represents overall folding of the polypeptide chain.
