NEETZoologyMolecular Basis of Inheritance
Term Definition A. Gene 1. A segment of DNA coding for a polypeptide. B. Cistron 2. Regulatory sequences that affect the expression of a gene but do not code for RNA or protein. C. Regulatory Gene 3. Functional unit of inheritance that may include coding and non-coding regions. D. Promoter 4. Sequence that provides the binding site for RNA polymerase and initiates transcription.
Options
- AA - 3, B - 1, C - 2, D - 4
- BA - 1, B - 2, C - 3, D - 4
- CA - 1, B - 3, C - 2, D - 4
- DA - 3, B - 2, C - 1, D - 4
Correct answer
A. A - 3, B - 1, C - 2, D - 4
Step-by-step solution
A - 3: A gene is a functional unit of inheritance that may include both coding and non-coding regions. B - 1: A cistron is a segment of DNA coding for a polypeptide. C - 2: Regulatory genes are sequences that affect gene expression but do not code for RNA or protein. D - 4: The promoter is a sequence that provides the binding site for RNA polymerase and initiates transcription.
