You are presented with the question "Where can cells bound by antibodies more likely be found?" and the following answer choices: 
- critical organs
 - colder and wetter
 - the environment
 - Earth orbiting the Sun
 - Veins and arteries.
 - epidermis and dermis
 - on cancer cells
 - the skin

Now knowing that antigens are found on cancer cells and the cells of transplanted organs and antibodies bound to antigen are then measured by RCAT-based amplification of the associated DNA tag, choose the best answer.
