Answer:
The correct answer is Retroviruses.
Explanation:
A virus having RNA as genetic material known as Retroviruses. These viruses have an enzyme, reverse transcriptase. Reverse transcriptase provides them the unique feature of transcribing RNA into DNA after the invasion into the host cell.
Retroviruses cells are either double-stranded DNA or single-stranded RNA. The examples of retroviruses are HIV, human T-lymphotropic virus type 1 (HTLV-1), and human T-lymphotropic virus type 2 (HTLV-II).
The type of virus that uses RNA and not DNA as it's genetic material is Retroviruses
Retroviruses are virus that has RNA as its genetic material. Retrovirus has enzymes called reverse transcriptase. Reverse transcriptase is an enzymes which catalyzes the formation of RNA from a DNA template during a process called reverse transcription.
A Retrovirus is a virus that belongs of the viral family called Retroviridae. It refers to a virus whose gene is encoded in RNA and not DNA. For Retroviruses to make copies of themselves, they need to make use of the organisms they infect. Though, infections by retrovirus involve many more steps. Retrovirus genome must be reverse-transcriptase into DNA before it can be copied in the normal way.
By using reverse transcription, retrovirus changes their single-stranded RNA to double-stranded DNA. The DNA stores the genome of the human cell as well as the cells from higher life forms.
The moment there is a transformation from RNA to DNA, the viral DNA will be integrated into genome of the cells that are infected, then DNA versions of the retroviral genes when incorporated into the genome will tricked down the cell into copying the gene as part of the replication process.
