Question

Quizplus · Accepted Answer

Ribosomes are essential for protein synthesis in all living organisms and are therefore highly conserved across the phylogenetic tree. Conserved DNA sequences of ribosomal RNA (rRNA) in the genes coding for ribosomes are often used for evolutionary studies and classification of microorganisms.
