1.	Can we use recent molecular tools to identify and classify organisms?
Answer» The recent molecular taxonomical tools can be used to identify and classify the organism. The following molecular techniques and approaches are used in molecular tools. (a) DNA bar coding – Short genetic marker in an organism’s DNA to identify whether it belongs to a particular species. (b) DNA hybridization – Measures the degree of genetic similarity between pools of DNA sequences. (c) DNA finger printing – to identify an individual from a sample of DNA by looking at unique patterns in their DNA. (d) Restriction Fragment Length Polymorphism (RFLP) Analysis- difference in homologous DNA sequences can be detected by the presence of fragments of different lengths after digestion of DNA samples. (e) Polymerase chain reaction (PCR) sequencing- to amplify a specific gene, or portion of gene.
