Retro virus - This is a type of virus that uses RNA as it genetic material. When a retrovirus  infects a cell, it makes a DNA copy of its genome that is inserted into the DNA of the host cell. There are a variety of different retroviruses  that cause human diseases, including the common cold, some forms of cancer, and AIDS.
