Question

ribosomal rna (rrna) nucleotide sequences are suitable for phylogenetic analysis of prokaryotes, because rrna is often a product of lateral gene transfer. performs functions unique to every organism. evolves relatively slowly and is present in all free - living organisms. is only present in certain species of bacteria. evolves rapidly.

Explanation:

Ribosomal RNA (rRNA) is a fundamental and conserved component across free - living organisms. It has a crucial and common function in protein synthesis. Its nucleotide sequences evolve relatively slowly, which makes it suitable for phylogenetic analysis to study evolutionary relationships among prokaryotes. It is present in all free - living organisms, not just certain bacteria, and is not a product of lateral gene transfer for this purpose, nor does it perform unique functions to every organism. It evolves slowly, not rapidly.

Answer:

evolves relatively slowly and is present in all free - living organisms.
