Through a collaboration between the Department of Chemistry and Chemical Biology and the Department of Molecular and Cellular Biology, researchers were able to take a snapshot of a stage of the mechanism by which the enzyme reverse transcriptase (RT) works on a strand of viral DNA to make new copies...
According to Harrison, when HIV enters a human cell, it uses RT and RNA to form a new strand of viral DNA. Then this strand is used to make another one,which when joined with the first, forms the fameddouble helix...
