A large variety of plants, animals, and microbes found on earth and they differ in size, shape, colour, habitat, and many other characteristics. So, studying each of them is impossible. Therefore, scientists have devised mechanisms to classify all living organisms on certain rules and principles that allow identification, nomenclature, and finally classification of an organism.
For example, based on presence of three pairs of legs and 2 pairs of wings, an organism is identified as an insect, it will be given a scientific name and then grouped with other similar organisms. Thus, various groups or taxon include organisms based on their similarity and differences.
Therefore, the biological classification helps in revealing the relationship between various organisms. It also helps in making study of organisms easy and organized.

Very good site
Nice answer sir
Nice description and thank you so much
Nice note
DNA fingerprinting is a technique used to identify and analyze the variations in various individuals at the level of DNA. It is based on variability and polymorphism in DNA sequences. DNA Fingerprinting Techniques: 1) Restriction endonuclease analysis of chromosome (REAC) 2) Restriction endonuclease analysis of plasmid DNA (REAP) 3) Restriction fragment length polymorphism (RFLP) 4) PCR-RFLP 5) Random amplified polymorphic DNA (RAPD) 6) Direct amplification fingerprinting (DAF) 7) Repetitive sequence-based PCR (rep-PCR) 8) Pulsed field gel electrophoresis (PFGE) 9) Amplified fragment length polymorphism (AFLP) 10) Single-strand conformational polymorphism (PCRSSCP) 11) Multilocus sequence typing (MLST)
plz answer this question What is DNA fingerprinting? Mention its techniques. best of luck
