MITOSIS Introduction Objectives: The first objective is to appreciate
... Mitosis is important in maintaining the DNA; every cell receives identical DNA from the mother cell, and continues it to pass it onto the following generation of cells. Mitosis is essential in the development and growth of an organism. The more mitosis that occurs, the more the organism can grow and ...

PRINCIPLES OF RECOMBINANT DNA TECHNOLOGY

After the foreign DNA has been incorporated into the plasmid the plasmid is introduced into the host bacterial cell by exposing the latter to calcium salts which make the cell membrane permeable to the plasmid. This is referred to as transformation. The next step is to grow the host-vector in cultur ...
