Quizplus · Accepted Answer

Carl Woese was a microbiologist who played a significant role in determining the sequence of rRNA molecules, which became an essential tool for classifying organisms. Based on his research, he proposed breaking prokaryotes into two domains and also proposed that eukaryotes be classified in a separate domain called Eukarya. Therefore, both option A and B are correct. Hence, the correct answer is E, which includes both options A and B.
