Final answer:
The primary transforming protein in HPV infection is E6, which binds to the tumor suppressor protein p53.the correct answer is E6
Step-by-step explanation:
The primary transforming protein in HPV infection is E6. HPV, or human papillomavirus, is an oncogenic virus that can lead to cervical cancer. One of the proteins encoded by the virus is E6, which binds to the tumor suppressor protein p53. When E6 binds to p53, it neutralizes the activity of p53, preventing it from halting the cell cycle or initiating apoptosis. This allows the virus-infected cells to continue rapid growth and accumulate mutations in the cellular DNA.
