You will be responsible for presenting a primary research article -- but what about all of that background material? In many cases, a picture is worth a thousand words when you are trying to explain complex ideas to your audience. Is there a great diagram to help explain the model system used in the study? Can you find an image to demonstrate the key cell cycle regulatory factors you are describing? Often review articles or other similar publications provided by publishers are a great source of these pictures and will be immensely useful as you try to convey the context of the research you are describing.
