How do retroviruses violate the central dogma?
Retroviruses are responsible for using DNA to synthesize more viral RNA
Retroviruses are pre-historic and existed prior to the central dogma
Retroviruses use enzymes to make DNA from RNA & integrate into host DNA
Retroviruses use host DNA to make viral RNA, then incorporate into host DNA
