Vedclass · Answer

(B) The sequence of $r-RNA$ (ribosomal $RNA$),specifically the $16S$ $r-RNA$ in prokaryotes and $18S$ $r-RNA$ in eukaryotes,is highly conserved across different species.Because these sequences change very slowly over evolutionary time,they are widely used as a molecular chronometer to determine evolutionary relationships and construct phylogenetic trees.

Which sequence is used to determine evolutionary relationships?
