Question
Retroviruses do not follow central Dogma. Comment.
✓

Answer

Francis and Crick proposed the central dogma in molecular biology. According to this, genetic information flows from DNA → RNA → Protein. In retroviruses, genetic information flows in reverse direction, i.e. Protein → RNA → DNA. Hence, it is said that retroviruses do not follow central dogma. The process followed by retroviruses is also called reverse transcription because of the opposite sequence of the process involved.
