It pulls you towards the ground therefore when we jump, or if you drop soemthing, it goes straight back down
DNA extraction from living cell
DNA is present inside nucleus surrounded by nuclear membrane. then cell is surrounded by plasma membrane, it means that DNA inside living cell is enclosed in two layers.
Removal of cell membrane
In order to remove cell membrane some detergents are applied followed by physical lysis through vertex.when the first cell membrane is pierced it is removed through centifugation by adding phenol and chloroform.
Removal of nuclear membrane
Proteinase enzyme is added which help in rupturing of nuclear membrane and removal of histone protein from DNA. Then RNAse is added to remove RNA from DNA.
Nucleus is present at the centre of atom. It contains protons and neutrons. It is very small as compared to the atom.
proton is the name for a nuclear particle that has about the same mass as a neutron, but with a positive charge.
