Final Answer:
Adenine pairs with Thymine in DNA, forming a complementary base pair. This pairing is fundamental to the double helix structure of DNA.
The correct option is, (c) adenine : DNA
Step-by-step explanation:
In the structure of DNA, adenine (A) always pairs with thymine (T) through hydrogen bonds, and similarly, guanine (G) pairs with cytosine (C).
This base-pairing specificity is crucial for maintaining the integrity and stability of the DNA molecule. The relationship between adenine and thymine is a key feature in DNA replication and the transmission of genetic information.
Therefore, the correct analogy is adenine : thymine :: Watson : Crick, where the pairing of adenine and thymine mirrors the collaborative partnership between James Watson and Francis Crick in elucidating the structure of DNA.
