On heating with concentrated ${\mathrm{HNO}}_3$ proteins give yellow colour. The test is called

The chemical name of vitamin ${\mathrm{B}}_1$ is

Adenosine is an example of

 Write the chemical name of ${\mathrm{B}}_1$ and name the disease caused by its deficiency.
 

Explain the role of nucleic acids in replication.

Name the types of bases in nucleotides of RNA.

A compound A$\left({\mathrm{C}}_6{\mathrm{H}}_{12}{\mathrm{O}}_6\right)$ is oxidised by bromine water into monobasic acid. It also reduces Tollen's reagent and reacts with $\mathrm{HCN}$ to give a compound B which on hydrolysis gives a compound C. On treating C with $\mathrm{HI}$ / red $\mathrm{P}$, n-heptanoic acid is obtained. Compound A on treatment with excess phenyl hydrazine gave D-glucosazone. Name the compound A and draw its cyclic form.
