The first step in dna isolation is called Homogenization.
In research, it is routine practise to isolate and purify DNA. The material must be homogenised in order to isolate DNA. The homogenization of glass beads or tissue with a mortar and pestle is a common method for doing this.
The first of these procedures entails pulverising the DNA with a mortar and pestle after adding liquid nitrogen. In order to break up the tissue, add the samples to tubes containing glass beads and quickly shake or vibrate the tube. Both approaches run the risk of severing the nucleic acid, especially the biggest fragments.
Therefore, The first step in dna isolation is called Homogenization
