Molecular methods are utilized in molecular biology, biochemistry, and genetics for the examination of DNA, RNA, and protein. Molecular cloning is the generally utilized Molecular technique. Molecular biology maintains the structure and capacity of macromolecules and furthermore about the association between DNA, RNA, protein and its biosynthesis. The distinctive techniques in molecular biology are Haemocytometer cell counter, Restriction chemical absorption, DNA ligation, transfection, western smear, plasmid filtration, electroporation, warm stun strategy, and ELISA. A standout amongst the most essential methods of molecular biology to consider protein work is molecular cloning. Molecular Biology methods are standard systems utilized as a part of biochemistry, molecular science, biophysics and hereditary qualities which for the most part include control and examination of DNA, RNA, lipid, and protein. Since around 1960, molecular researches have been created distinctive approaches to distinguish, detach and control sub-molecular segments in cells including DNA, RNA, and proteins.
