Pestle And Mortar For Plant Dna Extraction

Insect DNA Extraction Protocol

The following procedure for obtaining insect DNA is similar to a plant DNA extraction procedure (Saghai-Maroof et al. 1984) and relies on a nonionic detergent, hexadecyltrimethylammonium bromide (CTAB) to lyse cells. The resulting DNA is suitable for use as a template in polymerase chain reactions to generate RAPD markers or for Southern blotting.


Extraction of DNA in a Research Setting: In a conventional research setting, the first step in extracting DNA involves breaking open the cell's membrane by using physical or chemical means. Examples include the use of sonication (sonic waves), homogenization equipment (blender, french press, mortar and pestle) or selective detergent use.

The Basics of DNA Extraction – Alaska BioPREP Virtual Textbook

Bacterial cells have no nucleus. Their DNA is organized in rings or circular plasmids, which are in the cytoplasm. The DNA extraction process frees DNA from the cell and then separates it from cellular fluid and proteins so you are left with pure DNA. The three basic steps of DNA extraction are 1) lysis, 2) precipitation, and 3) purification.
