Frederick Sanger is a twice recipient of the Nobel Prize for

Physics in 1956 and 1972
Chemistry in 1958 and 1980
Physics in 1903 and Chemistry in 1911
Chemistry in 1954 and Peace in 1962

The correct answer is: B. Chemistry in 1958 and 1980.

Frederick Sanger was a British biochemist who won the Nobel Prize in Chemistry twice, in 1958 and 1980. He was awarded the prize in 1958 for his work on the structure of proteins, and in 1980 for his work on the sequencing of DNA.

Sanger’s work on proteins was groundbreaking. He developed a method for sequencing proteins, which allowed scientists to determine the order of the amino acids in a protein. This was a major advance in the field of biochemistry, and it paved the way for the development of new drugs and treatments.

Sanger’s work on DNA sequencing was also groundbreaking. He developed a method for sequencing DNA, which allowed scientists to determine the order of the nucleotides in a DNA molecule. This was a major advance in the field of genetics, and it paved the way for the development of new technologies, such as genetic engineering.

Sanger’s work has had a profound impact on the fields of biochemistry, genetics, and medicine. He is considered one of the most important scientists of the 20th century.

The other options are incorrect. Option A is incorrect because Sanger was not awarded the Nobel Prize in Physics. Option C is incorrect because Sanger was not awarded the Nobel Prize in Physics in 1903 or 1911. Option D is incorrect because Sanger was not awarded the Nobel Prize in Chemistry in 1954 or Peace in 1962.
