The total number of correct statements, regarding the nucleic acids is . A. RNA is regarded as the reserve of genetic information B. DNA molecule self-duplicates during cell division C. DNA synthesizes proteins in the cell D. The message for the synthesis of particular proteins is present in DNA E. Identical DNA strands are transferred to daughter cells.

Answer

3

Solution

As per NCERT: DNA stores the genetic message and replicates; RNA makes the proteins.

A: reserve of genetic information is DNA ⇒ A is false

B: DNA replicates during cell division ⇒ B is true

C: proteins are synthesised by RNA molecules ⇒ C is false

D: the message (genetic code) for a protein is in DNA ⇒ D is true

E: replication gives identical DNA to daughter cells ⇒ E is true

∴ Correct statements: B, D, E = 3

Answer: 3
