$r-RNA$

Vedclass · Answer

(B) The phylogenetic history of organisms is primarily determined by analyzing the sequence of $r-RNA$ (ribosomal $RNA$),specifically the $16S$ $r-RNA$ in prokaryotes and $18S$ $r-RNA$ in eukaryotes.$r-RNA$ genes are highly conserved across different species because they are essential for protein synthesis.Due to their slow mutation rate,they serve as an excellent 'molecular chronometer' to trace evolutionary relationships and construct phylogenetic trees.

Which sequence is used to determine the phylogenetic history of an organism?
