Correct Option
The correct option is A is true but R is false
Explanation
Reproduction involves the transmission of hereditary information from parents to offspring. This information is stored in the form of DNA (Deoxyribonucleic Acid). Therefore, the replication or copying of DNA is the fundamental prerequisite for any reproductive process to ensure continuity of genetic traits.
Statement-wise Analysis:
- Assertion (A): Correct. The creation of a DNA copy is indeed a basic event in reproduction. For an organism to reproduce, it must produce a copy of its genetic blueprint so that the new individual receives the necessary information to develop and function. This applies to both asexual and sexual reproduction.
- Reason (R): Incorrect. A DNA molecule cannot survive or function in isolation. It requires an organized cellular structure-including cytoplasm, organelles, and enzymes-to maintain life processes, synthesize proteins, and regulate metabolism. Consequently, DNA copying is always accompanied by the creation of an additional cellular apparatus (cell division/cytokinesis) to house the new DNA. If DNA were copied without the division of the cellular machinery, the new strand would not survive.
Key Takeaway:
DNA copying is essential for reproduction, but it is not sufficient on its own; it must be followed by cell division to provide the necessary cellular apparatus for the survival of the new genetic material.
