WebThe lack of 32 P-labeled DNA remaining in the solution after the bacteriophages had been allowed to adsorb to the bacteria showed that the phage DNA was transferred into the bacterial cell. The presence of almost all the radioactive 35 S in the solution showed that the protein coat that protects the DNA before adsorption stayed outside the cell. WebThe most common type of DNA vector is a bacterial plasmid, a small circular piece of DNA that grows in bacteria independent from the bacterial chromosome. Plasmids have multiple features that facilitate the cloning process. Multiple restriction sites (e.g., EcoRI) are indicated along the plasmid perimeter in the plasmid map. Restriction enzymes ...
