Question

Carl Woese proposed the domain classification a. using shape to classify microbial species b. to divide the single-celled organisms from the multicellular organisms. c. to account for two major and distinct prokaryotic groups in addition to eukaryotes. d. to replace kingdoms.

Answer 1

Answer:

c. to account for two major and distinct prokaryotic groups in addition to eukaryotes.

Explanation:

Microbiologist Carl Woese compared the ribosomal RNA sequence of the small subunit of RNA. Various organisms have structurally different small subunit of the ribosomes. According to Woese the molecular composition of rRNA in closely related organisms should be more similar than in distantly related organisms. He analyzed the 16S rRNA of various organisms and observed that there are two distinct groups of prokaryotes. He divided the prokaryotes among two domains: Bacteria and Archaea. He placed all the eukaryotes in the domain Eukarya.
