Molecular phylogenetics /mÉµËlÉkjÊlÉr ËfaÉªlÉµdÊÉ¨ËnÉtÉ¨ks/ is the branch of phylogeny that analyses hereditary molecular differences, mainly in DNA sequences, to gain information on an organism's evolutionary relationships. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree.Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography.olecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography.
1 If the genomic DNA sequence of a gene is known, RT-PCR can be used to map the location of exons and introns in the gene. 2  The 5' end of a gene (corresponding to the transcription start site) is typically identified by RACE-PCR (Rapid Amplification of cDNA Ends).
