Quizplus · Accepted Answer

Ribosomal RNA (rRNA) varies in sequence and length among different species, but its basic structure and function remain conserved. This makes it an ideal trait to analyze for estimating the evolutionary relationships between different organisms. rRNA is found in all living cells and is involved in protein synthesis, making it a useful tool for phylogenetic analyses.
