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. Now, the bacteria phage usually undergoes a pathway, a cycle known as the Litig cycle. But other types of bacteria exist that can or other types of viruses exist that can also undergo the lysogenic cycle. So when the virus enters the cell there are two types of pathways that can be taken by that virus.
