The chirality of DNA and RNA molecules are due to the presence of sugar components. 
Related Theory DNA have multiple chiral centres and are found as single enantiomers in nature. The DNA structure itself is chiral and exists as a single enantiomer.

Markovnikov's rule is applicable to:
Which of the following is a reducing sugar?
Name the class of enzyme that usually catalyze the following reaction : $\mathrm{S}-\mathrm{G}+\mathrm{S}^{\#} \rightarrow \mathrm{~S}+\mathrm{S}^{\#}-\mathrm{G}$ Where, $G \rightarrow$ a group other than hydrogen $S \rightarrow$ a substrate $\mathrm{S}^{\#} \rightarrow$ another substrate
Identify the suitable reagent for the following conversion 
Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A) : undergoes $\mathrm{S}_{\mathrm{N}} 2$ reaction faster than Reason (R) : Iodine is a better leaving group because of its large size. In the light of the above statements, choose the correct answer from the options given below :
