Question 1

True or false: Woese originally proposed three domains of life: Bacteria, Archaea, and Eukarya.

Accepted Answer

True. His 1990 paper with Kandler and Wheelis formally introduced the three-domain system, revolutionizing taxonomy.

Question 2

True or false: Carl Woese was born in Germany and immigrated to the United States as a child.

Accepted Answer

False. Woese was born in Syracuse, New York, in 1928, and grew up in the United States.

Question 3

True or false: Carl Woese discovered the domain Archaea by analyzing ribosomal RNA sequences.

Accepted Answer

True. Woese used rRNA sequencing in the 1970s to reveal Archaea as a separate domain from Bacteria and Eukarya.

Question 4

True or false: Woese won the Nobel Prize in Physiology or Medicine for his discovery of Archaea.

Accepted Answer

False. Woese never won a Nobel Prize, though he received other major awards like the Crafoord Prize.

Question 5

True or false: Woese's discovery of Archaea was immediately accepted by the scientific community in the 1970s.

Accepted Answer

False. His findings were initially met with skepticism and controversy, taking years to gain widespread acceptance.

Question 6

True or false: Carl Woese was a physicist who switched to microbiology later in his career.

Accepted Answer

False. Woese studied physics and biophysics at Yale, but he earned a PhD in biophysics, not physics, and became a microbiologist.

Question 7

True or false: Woese used a method called oligonucleotide cataloging to compare ribosomal RNA sequences.

Accepted Answer

True. This early technique involved digesting rRNA and analyzing fragments, leading to his groundbreaking phylogenetic tree.

Question 8

True or false: Woese believed the universal common ancestor was a primitive, RNA-based entity he called the 'progenote.'

Accepted Answer

True. He theorized the progenote had a primitive genetic code and was not yet fully cellular, predating the three domains.
