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.
A: CRISPR âspacerâ sequences are transcribed into short RNA sequences (âCRISPR RNAsâ or âcrRNAâ) capable of guiding the system to matching sequences of DNA. When the target DNA is found, Cas9 â one of the enzymes produced by the CRISPR system â binds to the DNA and cuts it, shutting the targeted gene off. Using modified versions of Cas9, researchers can activate gene expression instead of cutting the DNA. These techniques allow researchers to study the geneâs function.
