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.
CRISPR is a molecular tool that edits the genomes of cells and organisms. The technology uses the DNA-cutting enzyme Cas9, with the help of a guide RNA sequence, to find and modify genetic targets. Previously, researchers used a Cas9 endonuclease, an enzyme that cuts through both strands of DNA.
