Question

state the " central dogma" produced by Francis Crick. Are there any exceptions to it? Support your answer with a reason and an example.

Answer 1

Francis Crick proposed the Central dogma in molecular biology, which states that the genetic information
flows from DNA → RNA → Protein.



In some viruses, central dogma is seen in the reverse direction, that is from RNA to DNA. as RNA is the main genetic material.
Eqs: Retrovirus (HIV) and the process is Reverse transcription.
