Which of the following is a characteristic of retroviruses?
  1. Contain DNA only
  2. Use RNA as their genetic material
  3. Replicate in the nucleus
  4. Are non-infectious

Questions & Step-by-Step Solutions

Which of the following is a characteristic of retroviruses?
  • Step 1: Understand what a retrovirus is. A retrovirus is a type of virus that has RNA as its genetic material.
  • Step 2: Learn that retroviruses can infect host cells. When they enter a host cell, they use their RNA.
  • Step 3: Know that retroviruses have a special enzyme called reverse transcriptase. This enzyme helps convert their RNA into DNA.
  • Step 4: Realize that once the RNA is converted into DNA, it can integrate into the host cell's DNA.
  • Step 5: Conclude that the main characteristic of retroviruses is that they use RNA and convert it into DNA inside the host cell.
