The correct Answer is:
To answer the question "Adenine pairs with thymine through," we will analyze the bonding between these two nucleobases in DNA. ### Step-by-Step Solution: 1. **Identify the Bases**: Recognize that adenine (A) and thymine (T) are both nitrogenous bases found in DNA. 2. **Understand Base Pairing**: In DNA, adenine pairs specifically with thymine. This pairing is crucial for the structure of the DNA double helix. 3. **Determine the Type of Bond**: The pairing between adenine and thymine is facilitated by hydrogen bonds. 4. **Count the Hydrogen Bonds**: It is known that adenine forms two hydrogen bonds with thymine. These bonds are responsible for stabilizing the base pairing in the DNA structure. 5. **Conclusion**: Therefore, the answer to the question is that adenine pairs with thymine through **two hydrogen bonds**. ### Final Answer: Adenine pairs with thymine through **two hydrogen bonds**. ---

Read the below Statements about the structure of genetic material and identify the correct ones. I. Adenine and guanine are bases that have a double ring structure , cytosine, thymine and uracil are based with a single ring structure . II. An adenine nucleotide from DNA is the same as an adenine nucleotide from RNA , DNA adenine pairs with uracil and RNA adenine pairs with thymine. III. The base pairing that occurs in a double DNA helix and when RNA is synthesised during transcription follows the rule that a purine pairs with a pyrimidine. IV. The two Polynucleotides on a DNA molecule run in opposite directions so that the double helix formed has two strands that are anti-parallel to each other.
