Question

Quizplus · Accepted Answer

The phylogenetic classification of bacteria is based on rRNA sequences, as they provide the most consistent and reliable means of determining evolutionary relationships between organisms. Other characteristics such as cell morphology, Gram reaction, and habitat may also be considered, but they are less important for determining overall evolutionary relationships. Diseases caused by bacteria are not a relevant factor in phylogenetic classification.
