Introduction:
The question is about the type of virus that contains both RNA and DNA.
Answer:
The correct answer is Leukovirus.
Explanation:
Viruses are classified based on their genetic material, which can be either DNA or RNA. However, some viruses have both RNA and DNA. These are called retroviruses, which are a type of single-stranded RNA virus that uses reverse transcriptase to convert its RNA genome into DNA. This DNA then integrates into the host cell's genome and is replicated along with the host DNA.
Examples of viruses with both RNA and DNA:
1. Hepatitis B virus
2. Hepatitis D virus
3. Human T-lymphotropic virus (HTLV)
4. Leukovirus
Leukovirus:
Leukovirus is a type of retrovirus that infects leukocytes, which are white blood cells. It is also known as human T-cell leukemia virus (HTLV) and is associated with various diseases, including adult T-cell leukemia and HTLV-associated myelopathy/tropical spastic paraparesis.
Conclusion:
In conclusion, of the given options, Leukovirus is the only virus that contains both RNA and DNA. It is important to note that retroviruses are the only known viruses that contain both RNA and DNA.
