rDNA analysis provides information on Phylogenetic relationships.
Ribosomal DNA (rDNA) is a DNA sequence that codes for ribosomal RNA. These sequences regulate transcription initiation and amplification and contain both transcribed and non-transcribed spacer segments.
The genes that are responsible for encoding the various sub-units of rRNA are located across multiple chromosomes in humans.
