Yes, white rice does have DNA.
While it is true that a significant portion of the white rice we consume comes from a specific genetic mutation, it's crucial to understand that this mutation is a deletion of a portion of DNA, not a complete absence of DNA. As such, the rice still has DNA.
The Genetic Basis of White Rice
According to researchers at Cornell University, approximately 97.9% of all white rice originates from a mutation—specifically a deletion—in a single gene within the Japonica subspecies of rice. This exact same mutation is also found in the Indica subspecies.
Key Points to Understand:
- Mutation, not Extinction: The reference speaks of a deletion of DNA, which indicates the removal of a section of DNA sequence within the rice genome. It does not mean that DNA is entirely absent.
- DNA is Fundamental: DNA is the genetic material essential for the functioning of all cells and is present in all living organisms, including plants like rice.
- Processing Doesn't Eliminate DNA: Even if the rice is processed (husk removed, polished) to become white rice, the cells still contain DNA.
In Summary
Despite the significant mutation leading to the characteristic properties of most white rice, it still has DNA. It is essential to remember the term "deletion" implies a removal, and not a complete absence of the genetic information.
