To solve this problem, we need to match the given names with their correct associations. Let's analyze each option:$\newline \bullet$Option 1: T.H. Morgan - Transduction$\newline$ - T.H. Morgan is known for his work on fruit flies (Drosophila) and the discovery of sex-linked inheritance, not transduction.$\newline$ - Transduction is a process of gene transfer in bacteria mediated by bacteriophages.$\newline$ - Therefore, this match is incorrect.$\newline \bullet$Option 2: F$_2 \times$Recessive parent - Dihybrid cross$\newline$ - An F$_2$ generation is typically the result of crossing two F$_1$ individuals.$\newline$ - A dihybrid cross involves two traits, but F$_2 \times$Recessive parent is a test cross, not specifically a dihybrid cross.$\newline$ - Therefore, this match is incorrect.$\newline \bullet$Option 3: Ribozyme - Nucleic acid$\newline$ - Ribozymes are RNA molecules that have catalytic activity.$\newline$ - They are indeed nucleic acids, as they are composed of RNA.$\newline$ - Therefore, this match is correct.$\newline \bullet$Option 4: G. Mendel - Transformation$\newline$ - G. Mendel is known as the father of genetics for his work on inheritance patterns in pea plants.$\newline$ - Transformation is a process of genetic alteration in bacteria, discovered by Frederick Griffith.$\newline$ - Therefore, this match is incorrect.$\newline$Based on the analysis, the correct match is:$\newline$Option 3: Ribozyme - Nucleic acid$\newline$This corresponds to the correct option, which is Option 3.
