The correct Answer is:
To solve the matching question, we will go through each individual in Column I and identify their contributions to the field of molecular biology, then match them with the appropriate items in Column II. ### Step-by-Step Solution: 1. **F. Miescher**: - Contribution: Friedrich Miescher was the first to identify and isolate the genetic material from the nuclei of cells in 1869, which he termed "nuclein". - Match: **A - 2 (Nuclein)** 2. **Griffith**: - Contribution: In 1928, Frederick Griffith conducted experiments that demonstrated the process of transformation in bacteria, using the bacterium *Streptococcus pneumoniae*. This experiment showed that genetic material could be transferred between bacteria. - Match: **B - 3 (Streptococcus pneumoniae)** 3. **Hershey and Chase**: - Contribution: In 1952, the Hershey-Chase experiment used bacteriophages (viruses that infect bacteria) to provide evidence that DNA is the genetic material, confirming that DNA, not protein, carries genetic information. - Match: **C - 4 (Bacteriophage)** 4. **Watson and Crick**: - Contribution: James Watson and Francis Crick are famous for proposing the double helix structure of DNA in 1953, which is fundamental to understanding genetic inheritance. - Match: **D - 1 (DNA double helix)** 5. **Wilkins and Franklin**: - Contribution: Maurice Wilkins and Rosalind Franklin conducted X-ray diffraction studies that were crucial in revealing the helical structure of DNA. - Match: **E - 5 (X-ray diffraction studies)** ### Final Matches: - A - 2 (Nuclein) - B - 3 (Streptococcus pneumoniae) - C - 4 (Bacteriophage) - D - 1 (DNA double helix) - E - 5 (X-ray diffraction studies) ### Summary of Matches: - A → 2 - B → 3 - C → 4 - D → 1 - E → 5
