Explanation:
Central dogma explains the flow of genetic information of the living organism. The DNA is converted to RNA by transcription and further into protein product by the process of translation. DNA can increase its number by replication process.
Retroviruses do not follow the central dogma and they have the ability to convert the RNA into the DNA molecule by the enzyme reverse transcriptase. Their central dogma is as follows:
DNA ⇄ RNA → PROTEINS.
Thus, the answer is DNA ⇄ RNA → PROTEINS.
