Question

Which of the following is a false statements?

• A. DNA is chemically less reactive, as compared to RNA.
• B. RNA mutate at a faster rate, as compared to DNA.
• C. Guanyl transferase enzyme helps in capping process during splicing of hn-RNA.
• D. Sweetness index of saccharine is 10,000.

Answer 1

The correct option is D Sweetness index of saccharine is 10,000.

DNA is chemically less reactive as compared to RNA.
RNA mutate at a faster rate because from DNA, RNA is formed duirng transcription and there are more chances of mutation during this phase.
Saccharin is an artificial sweetener with effectively no food energy which is about 300-400 times as sweet as sucrose.
hnRNA is heterogenous nuclear RNA. Its processing includes addition of a cap. The cap is 5'methyl guanosine that is added immediately after the start of the transcription. This reaction is catalysed by guanylyl transferase.
