One mechanism by which viruses may cause cancer is to interrupt the genetic regulatory sequences of repressor proteins. Which of the following types of viruses is most likely to be involved in causing cancer by this mechanism?

retroviruses
hetroviruses
misoviruses

retroviruses

Explanation:

Retroviruses appear to cause cancer in their host by mutating the host gene sequences allowing for the activation of some potentially oncogenic genes to be expressed. They do this by inserting their proviral DNA into the host genome at specific regulatory sequences deregulating cellular signaling and transcriptional controls.
