Question

Select the correct match :

• A. Ribozyme – Nucleic acid
• B. T.H. Morgan – Transduction
• C. F₂ × Recessive parent – Dihybrid cross
• D. G. Mendel – Transformation

Answer 1

The Correct Option is A

To solve this question, we need to correctly match terminologies related to biology with their definitions or associated scientists. Let's analyze each option:

1. Ribozyme – Nucleic acid: This is correct. Ribozymes are RNA molecules that function as enzymes. They play a crucial role in catalyzing certain biochemical reactions. As nucleic acids, they are made up of nucleotides, which are the building blocks of RNA. Hence, this match is accurate.
2. T.H. Morgan – Transduction: This is incorrect. T.H. Morgan is renowned for his work in genetics, particularly for discovering the role of chromosomes in heredity using Drosophila (fruit flies). Transduction, however, is a different process related to the transfer of DNA from one bacterium to another via a virus, which was not his area of primary focus.
3. F₂ × Recessive parent – Dihybrid cross: This is incorrect. A dihybrid cross typically involves two organisms that are heterozygous for two traits. Crossing F₂ offspring with a recessive parent is an example of a test cross to determine the genotype of the F₂ organisms, not a dihybrid cross.
4. G. Mendel – Transformation: This is incorrect. G. Mendel is known as the father of genetics for his work on the inheritance of traits in pea plants, leading to the development of Mendel's Laws of Inheritance. Transformation refers to the genetic alteration of a cell resulting from the direct uptake and incorporation of exogenous genetic material, a concept later discovered in the context of bacterial genetics, not directly by Mendel.

Based on the above analysis, the correct match is Ribozyme – Nucleic acid.
