उत्तर
Information from DNA to mRNA (Transcription) and from mRNA to protein (Translation).
This can be represented as:
\[\ce{DNA ->[transcription] mRNA ->[translation] Protein}\]
However, in some retroviruses, reverse transcription takes place due to which DNA is synthesized from RNA. This can be represented as:
\[\ce{DNA <=>[Transcription][Reverse Translation] mRNA ->[Translation] Protein}\]
