ok what does the lysogenic cycle do??

so...i guess you're referring to viruses' life cycle. viruses can develope either lysogenically or in a litic way once they enter the host cell. while litic viruses exploit the cell so that it produces copies of the virus and then releases them literally exploding (and therefore dying), lisogenic ones integrate their genome into the host's genome. this mainly happens when the virus senses that the host isn't "in shape" and couldn't therefore afford the cost of copying the virus. viruses have complicate mechanisms to sense the status of the host, it would be very difficult to explain it in brief. just keep it in mind. so, the virus chooses to "hide" in the host genome in precise positions and wait for the right conditions to come. the host will grow and reproduce. all the descendants will have the integrated virus genome in their DNAs, so the virus will be copied together with the genomic DNA and spread in multiple copies to a great number of cells. when the environmental conditions become good enough to guarantee to cells to be "in shape", the virus senses it (once more the mechanism is very clever) and its genome excides itself from the host genome and forces the cell to produce copies of it (it becomes litic). this happens simultaneously in all the cells generated from the originally infected host. as you can imagine, the number of viruses thus produced is veeeeeeeeeeeeeeery high!
