Cornell researchers have answered a fundamental question about how two strands of DNA separate to start a process called replication, in which genes copy themselves. The research examined the role of an enzyme called a helicase, which plays a major role in separating DNA strands. Share: FULL STORY.
DNA extraction. DNA (DeoxyriboNucleic Acid) is a long stringy molecule that can be extracted from any biological material such as living or conserved tissues, cells and virus particles.A number of basic procedures are carried out to isolate and purify DNA.First the cell is broken open to expose its DNA. This is achieved by blending or grinding the cell. The next step involves breaking down and emulsifying the fat and proteins that make up the cell's membrane. number of basic procedures are carried out to isolate and purify DNA.
