Frederick Sanger won the Nobel Prize twice in which field?

  • Physics in 1956 and 1972
  • Chemistry in 1958 and 1980
  • Physics in 1903 and Chemistry in 1911
  • Chemistry in 1954 and Peace in 1962
Correct Answer: B. Chemistry in 1958 and 1980

Detailed Explanation

Frederick Sanger was a pioneering British biochemist who made groundbreaking contributions to molecular biology and genetics. He is famously known as the only person to have won the Nobel Prize twice in Chemistry. His first Nobel Prize, awarded in 1958, was for determining the amino acid sequence of insulin, which was a monumental achievement in understanding protein structure. His work demonstrated that proteins have a definite chemical structure, which was a major advancement in biochemistry.


Sanger's second Nobel Prize, awarded in 1980, was shared with Paul Berg and Walter Gilbert for their contributions to DNA sequencing methods. Sanger developed the dideoxy sequencing method, also known as Sanger sequencing, which became a fundamental technique for analyzing DNA sequences. This method revolutionized genetics, genomics, and biotechnology, and laid the foundation for projects like the Human Genome Project.


Other options in the question are incorrect:




  • Physics-related options are unrelated to Sanger’s work.




  • Peace or Nobel Prizes in other years do not correspond to Sanger’s achievements.




Sanger’s work had profound implications in medicine and biology. Understanding protein structures helped in the development of drugs and insulin therapy, while DNA sequencing has enabled genetic research, disease diagnosis, and biotechnology innovations. His achievements highlight the intersection of chemistry, biology, and molecular genetics.


In summary, Frederick Sanger is celebrated for winning the Nobel Prize twice in Chemistry (1958 and 1980), marking him as one of the most influential scientists of the 20th century. His work continues to impact genetics, medicine, and biochemistry, making him a key figure in the study of life sciences
