We have our nucleic acids, either DNA or RNA, found inside the protein capsule. This is the protein capsule also known as the head of our bacteria phage. We also have a protein midsection as well as the protein tail. And in order to actually attach the virus onto the cell membrane of the bacteria, this tail, the bottom portion of the tail, actually has to attach to the proper receptor on the cell membrane of that bacteria. And once our attachment actually takes place so following attachment, our bacteria phase injects the nucleic acid, either DNA or RNA, never both into the cytoplasm of the cell. And within a short period of time the cell begins to basically translate and synthesize the proteins encoded by the viral nucleic acid.
