Correct option is B
The correct answer is: (B) Its stable double-helical structure
Explanation:
- The double-helix structure of DNA is what makes it stable and reliable as a medium for storing genetic information. This stable structure allows DNA to be passed on accurately during cell division, ensuring the persistence of genetic information across generations.
- The structure consists of two complementary strands of nucleotides twisted into a helix, providing resistance to damage and allowing for effective replication and transcription. This stability contributes to DNA's abundance as the primary genetic material in most organisms.
Information Booster:
- DNA's stability is key to its role in inheritance. The double-helical structure helps protect the genetic material from external damage and allows for repair mechanisms to fix any errors or damage.
- RNA, though involved in genetic processes, is less stable and more prone to degradation than DNA, making DNA the preferred medium for long-term genetic storage.
Additional Information:
- Its high mutation rate: Incorrect. A high mutation rate would actually be detrimental to genetic stability, not an advantage for genetic material.
- Its enzymatic roles: Incorrect. DNA does not have enzymatic roles. Proteins like enzymes are responsible for many cellular functions, not DNA itself.
- Its interaction with proteins: Incorrect. While DNA interacts with proteins (e.g., histones in chromosomes), this interaction is more about regulation and packaging, not the reason for its abundance.
