The correct Answer is:
To answer the question "In a DNA molecule adenine of one strand base pairs with ………. on the other strand," we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Structure of DNA**: - DNA (Deoxyribonucleic Acid) is a double-stranded molecule that carries genetic information. It consists of two strands that twist around each other to form a double helix. 2. **Identify the Nitrogenous Bases**: - The nitrogenous bases in DNA are adenine (A), thymine (T), guanine (G), and cytosine (C). 3. **Know the Base Pairing Rules**: - In DNA, specific nitrogenous bases pair with each other: - Adenine (A) pairs with Thymine (T) - Guanine (G) pairs with Cytosine (C) 4. **Apply the Base Pairing Rule**: - Since the question asks what adenine pairs with on the other strand, we refer to the base pairing rules. Adenine pairs with thymine. 5. **Conclude the Answer**: - Therefore, in a DNA molecule, adenine of one strand base pairs with thymine on the other strand. ### Final Answer: Adenine pairs with Thymine (T). ---

Assertion :- Complementary base pairing confers a very unique property to the DNA chains. Reason : If sequence of one strand is known then sequence in other strand can be predicted.

If the sequence of bases in one strand of DNA is known then the sequence in other strand can be predicted on the basis of -

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.
