Question

Quizplus · Accepted Answer

Two organisms with similar rRNA sequences are likely to have evolved from a common ancestor. rRNA is highly conserved and evolves at a relatively slow rate, making it a useful tool for studying evolutionary relationships between organisms. By comparing rRNA sequences, scientists can construct phylogenetic trees that show the evolutionary history and relatedness of different species.
