The driving question behind my video is ," What are viruses? How does the structure of the virus relate to it's ability to infect cells, replicate,and cause disease?" Viruses are microscopic agents that replicate  within the cells of living hosts. The Bacteriophage T4 attaches itself to the host cell  and inserts it's own DNA ,which is located in the head, into the cell. The DNA then undermines the cell's normal actions, and uses the cell's system to create replicas of itself, which then float off and repeat the process..
