Can we use recent molecular tools to identify and classify organisms?

Explanation

Yes, we can.
Molecular taxonomical tools : Technological advancement has helped to evolve molecular taxonomical tools from classical tools to molecular tools. The accuracy and authenticity is more significant in the molecular tools.
1. The following methods are being used for taxonomical classification.
a) DNA barcoding - Uses short genetic marker in an organism's DNA to identify it as belonging to a particular species.
b) DNA hybridization - measures degree of genetic similarity between pools of DNA sequences.
c) DNA fingerprinting - to identify an individual from a sample of DNA by looking at unique patterns in their DNA.
d) Restriction Fragment Length Polymorphisms (RFLP) analysis - difference in homologous DNA sequences that can be detected by the presence of fragments of different lengths after digestion of the DNA samples.
e) Polymerase Chain Reaction (PCR) - sequencing to amplify a specific gene, or portion of gene.
II. Neo taxonomical tools-This is based on Electron Microscopy images to study the molecular structures of cell organelles.
