The correct Answer is:
To solve the question "In transcription of RNA from DNA, thymine will form a base pair only with," we need to understand the base pairing rules in DNA and RNA transcription. ### Step-by-Step Solution: 1. **Identify the Nitrogenous Bases in DNA**: - DNA consists of four nitrogenous bases: Adenine (A), Thymine (T), Cytosine (C), and Guanine (G). 2. **Understand Base Pairing in DNA**: - In DNA, the base pairing rules are: - Adenine (A) pairs with Thymine (T) through two hydrogen bonds. - Cytosine (C) pairs with Guanine (G) through three hydrogen bonds. 3. **Consider the Process of Transcription**: - During transcription, RNA is synthesized from a DNA template. In RNA, Thymine (T) is replaced by Uracil (U). - However, when considering the original DNA strand, Thymine (T) will still pair with Adenine (A) during the transcription process. 4. **Determine the Correct Pairing for Thymine**: - According to the base pairing rules, Thymine (T) in DNA will only form a base pair with Adenine (A). 5. **Evaluate the Options Given**: - The options provided are: - A) Cytosine - B) Guanine - C) Adenine - D) Thymine - Based on our analysis, Thymine (T) pairs with Adenine (A). 6. **Select the Correct Answer**: - Therefore, the correct answer is **C) Adenine**.

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.
