DNA isolation is a process of purification of DNA from sample using a combination of physical and chemical methods.The first isolation of DNA was done in 1869 by Friedrich Miescher. Currently it is a routine procedure in molecular biology or forensic analyses. Breaking the cells open, commonly referred to as cell disruption or cell lysis, to expose the DNA within. 2  This is commonly achieved by chemical and physical methods-blending, grinding or sonicating the sample. 3  Removing membrane lipids by adding a detergent or surfactants which also serves in cell lysis.
Best Answer: The term ligation in molecular biology basically means the joining of two molecules (usually nucleotides). A ligase is an enzyme that facilitates this process. In DNA replication, the purpose of DNA ligase is to ligate the nucleotides in the lagging strand to one another.ubmit. Â· just now. Report Abuse. Binds strands of DNA together, of ligates them. During replication when DNA is sythesizing they unbind at points. DNA ligase is a particular type of ligase that can link together DNA strands that have double-strand breaks (a break in both complementary strands of DNA).
