The correct answer is option 'B', the discovery of the structure of DNA by Watson and Crick.
Explanation:
The year 2003 was indeed celebrated as the 50th anniversary of the discovery of the structure of DNA by James Watson and Francis Crick. This groundbreaking discovery revolutionized the field of genetics and laid the foundation for modern molecular biology.
Key Points:
- The structure of DNA refers to its double helix shape, which consists of two long strands of nucleotides twisted around each other.
- Watson and Crick, along with their colleague Rosalind Franklin, made this discovery in 1953 while working at the University of Cambridge.
- Their breakthrough was based on the X-ray crystallography images of DNA taken by Franklin, which revealed the helical nature of the molecule.
- Using these images, along with existing research and their own insights, Watson and Crick proposed the double helix model of DNA.
- This model showed that DNA is composed of two complementary strands held together by hydrogen bonds between the paired nucleotides.
- The discovery of the structure of DNA provided a mechanism for understanding how genetic information is stored and transmitted in living organisms.
- It also paved the way for further research in molecular biology, genetics, and biotechnology.
- Watson, Crick, and Maurice Wilkins were awarded the Nobel Prize in Physiology or Medicine in 1962 for their work on the structure of DNA.
- The 50th anniversary of this milestone in scientific history was celebrated worldwide in 2003, acknowledging the significance of this discovery and its lasting impact on our understanding of life and genetics.
In conclusion, the correct answer to the question is option 'B', the discovery of the structure of DNA by Watson and Crick. This discovery was a major milestone in the field of genetics and had a profound impact on our understanding of life and inheritance.
