The figure illustrates an important concept in the genetic implication of $DNA$. Fill in the blanks $A, B$,and $C$.

Read the following statements and select the correct statements:
$(A)$ Essential life processes such as metabolism,translation and splicing are evolved around $\text{RNA.}$
$(B)$ Heavy isotope of nitrogen $(^{15}N)$ is a radioactive isotope,while light isotope of nitrogen $(^{14}N)$ is not a radioactive isotope.
$(C)$ The codon in $\text{rRNA}$ is read in a contiguous fashion.
$(D)$ In the first phase of translation,amino acids are activated in the presence of $\text{ATP.}$
$(E)$ $\text{DNA}$ from every tissue from an individual shows a high degree of polymorphism.
Choose the correct answer from the options given below:

For protein synthesis,$P$ can directly code,while each nucleotide of $Q$ has a $2'-OH$ group in its sugar. Identify $P$ and $Q$.
$\quad\quad P\quad Q$
