NEETZoologyMolecular Basis of Inheritance
In living systems, DNA is preferred for the storage of genetic information, whereas RNA is preferred for the transmission of genetic information. Which of the following pairs of properties best justifies this functional division?
Options
- ADNA can directly code for the synthesis of proteins, whereas RNA is chemically highly stable and resists mutat
- BDNA has a higher mutation rate facilitating rapid evolution, whereas RNA acts exclusively as a structural comp
- CDNA is chemically less reactive and structurally more stable, whereas RNA can directly code for the synthesis
- DDNA is single-stranded making it compact for storage, whereas RNA contains thymine making it suitable for tran
Correct answer
C. DNA is chemically less reactive and structurally more stable, whereas RNA can directly code for the synthesis
Step-by-step solution
According to NCERT, DNA is chemically less reactive and structurally more stable compared to RNA, which makes it a better genetic material for the storage of genetic information. On the other hand, RNA is preferred for the transmission of genetic information because it can directly code for the synthesis of proteins. DNA is dependent on RNA for protein synthesis. The other options contain incorrect biological facts: DNA does not directly code for proteins, RNA is not highly stable, DNA does not have a higher mutati
