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

Evaluating each statement concerning nucleic acids:

Statement A: RNA is considered the repository for genetic information.
Evaluation: False. DNA functions as the primary reservoir of genetic information, while RNA participates in protein synthesis.

Statement B: A DNA molecule duplicates itself during cell division.
Evaluation: True. DNA replication occurs during the S phase of the cell cycle, ensuring genetic information is transmitted to daughter cells.

Statement C: DNA synthesizes proteins within the cell.
Evaluation: False. DNA acts as a template for mRNA synthesis, which is subsequently translated into proteins, rather than directly synthesizing proteins.

Statement D: The instructions for synthesizing specific proteins are contained within DNA.
Evaluation: True. DNA encompasses the sequences (genes) that encode for proteins.

Statement E: Identical DNA strands are passed to daughter cells.
Evaluation: True. Each daughter cell is provided with an identical DNA copy through DNA replication.

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

Therefore, the total count of accurate statements about nucleic acids is: 3
