Multiple Choice
Which of the following are the three domains proposed in Woese's classification system?
A
Bacteria, Archaea, Eukarya
B
Bacteria, Protista, Eukarya
C
Bacteria, Fungi, Eukarya
D
Archaea, Protista, Eukarya
0 Comments
Verified step by step guidance1
Understand that Woese's classification system is based on genetic differences in ribosomal RNA (rRNA) sequences.
Recognize that the three domains proposed by Carl Woese are Bacteria, Archaea, and Eukarya.
Bacteria and Archaea are both prokaryotic domains, meaning they lack a nucleus, but they have distinct genetic and biochemical differences.
Eukarya is the domain that includes all eukaryotic organisms, which have cells with a nucleus, such as plants, animals, and fungi.
Review the options given and identify that the correct set of domains according to Woese's classification is Bacteria, Archaea, and Eukarya.
