Retroviruses use reverse transcriptase to make a DNA copy of their RNA genome for subsequent integration into the host DNA. This changed the course of molecular biology and made scientists revisit the central dogma. Reverse transcriptase is now used extensively by molecular biologists in the laboratory to convert RNA into DNA. Describe why you believe reverse transcriptase is so extensively used by modern molecular biologists. What problem does our ability to convert RNA into DNA solve and what can we.
