The sweetness index of saccharin is $10,000$.

(D) Option $D$ is incorrect. The sweetness index of saccharin is approximately $300$ to $500$ times that of sucrose,not $10,000$. $DNA$ is chemically less reactive and structurally more stable than $RNA$ due to the absence of the $2'-OH$ group. $RNA$ is more labile and prone to mutations,making it evolve faster. Guanylyl transferase is indeed the enzyme responsible for adding the $7-methylguanosine$ cap to the $5'$ end of $hn-RNA$ during processing.
