Which of the following organic compounds is the main source of energy for living things?a.carbohydratesc.nucleic acidsb.lipidsd.

gizmo_the_mogwai [7]

Answer:

Inosine

Explanation:

  • Inosine the unusual nucleoside which is found in tRNA but not in mRNA.
  • Inosine is derived from the nucleoside adenosine, adenosine is present in mRNA, however in case of tRNA, there is deamination of adenosine and thus, inosine is formed.
  • The enzyme that is responsible for carrying out this reaction is called as tRNA A:34 deaminases, here the position 34 indicates that the deamination takes place at position 34 of the tRNA.
  • The formation of inosine is essential for the wobble base pairing to take place.
  • The formation of inosine takes place when the hypoxanthine attaches to a ribose ring with the help of the beta glycosidic bond.
