Question

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 1

Correct Answer: 3

Let’s evaluate each statement regarding nucleic acids:

Statement A: RNA is regarded as the reserve of genetic information.
Evaluation: False. DNA is the primary genetic material that serves as the reservoir of genetic information, while RNA plays a role in protein synthesis.

Statement B: DNA molecule self-duplicates during cell division.
Evaluation: True. DNA replication occurs during the S phase of the cell cycle, allowing genetic information to be passed to daughter cells.

Statement C: DNA synthesizes proteins in the cell.
Evaluation: False. DNA itself does not synthesize proteins; rather, it serves as a template for mRNA synthesis, which then translates to proteins.

Statement D: The message for the synthesis of particular proteins is present in DNA.
Evaluation: True. DNA contains the sequences (genes) that code for proteins.

Statement E: Identical DNA strands are transferred to daughter cells.
Evaluation: True. During DNA replication, each daughter cell receives an identical copy of DNA.

Summary of Correct Statements: Correct statements: B, D, and E.

Thus, the total number of correct statements regarding nucleic acids is: 3
