Answer:
The virus in which RNA acts as a genetic material and no DNA is involved.
Step-by-step explanation:
Central dogma was discovered by Crick. This central dogma explains the floe of genetic information from DNA to RNA to protein. DNA can be replicated by the process of replication.
Central dogma is applicable only for the protein coding genes. The virus that uses RNA dependent RNA polymerase that produces RNA form the RNA molecule and shows RNA replication. The DNA is not involved in their genetic process. Example : Cystoviridae, Reoviridae and Monoegavirales.
