Question 1

True or false: Sanger personally sequenced the entire human genome by hand in the 1990s.

Accepted Answer

False. The Human Genome Project was a massive international effort; Sanger retired in 1983 and never attempted whole-genome sequencing himself.

Question 2

True or false: Sanger's first Nobel Prize was for developing the Sanger sequencing method.

Accepted Answer

False. His 1958 Nobel was for determining the amino acid sequence of insulin, not DNA sequencing. The Sanger method came later, winning his second Nobel in 1980.

Question 3

True or false: Frederick Sanger is the only person to have won two Nobel Prizes in Chemistry.

Accepted Answer

True. He won the 1958 Nobel for insulin structure and the 1980 Nobel for DNA sequencing, making him a double laureate in chemistry alone.

Question 4

True or false: Sanger's second Nobel Prize was shared with two other scientists for developing recombinant DNA technology.

Accepted Answer

False. His 1980 Nobel in Chemistry was shared with Walter Gilbert and Paul Berg, but for DNA sequencing (Sanger and Gilbert) and recombinant DNA (Berg), not solely recombinant technology.

Question 5

True or false: Sanger's DNA sequencing method was based on using radioactive phosphorus to label DNA fragments.

Accepted Answer

False. His method used dideoxynucleotides to terminate DNA strands, not radioactive phosphorus. Radioactive labeling was used in detection, but the core innovation was chain termination.

Question 6

True or false: Sanger originally studied physics at university before switching to biochemistry.

Accepted Answer

True. He began studying physics at Cambridge but found it too abstract, switching to biochemistry after his first year—a move that shaped his career.

Question 7

True or false: Sanger was awarded the Nobel Prize twice, but never gave a Nobel lecture for his first award.

Accepted Answer

True. He did not deliver a lecture for his 1958 Nobel because he was too shy and felt he had nothing new to say, though he later gave one for his 1980 prize.

Question 8

True or false: Sanger refused a knighthood because he disliked formal titles.

Accepted Answer

True. He declined a knighthood in 1963 and later refused a peerage, preferring to avoid public attention and focus solely on his research.
