"I believe this interview has been quite informative because I love what I've learned about Gilead Sciences and what daily life would be like on your team as a new graduate. Despite my nerves, I am happy with my performance. Is there anything that I can clarify for you from this conversation?"

"I'd love to go back to the question you asked on my desire to further my education in my career, as I didn't portray my entire thoughts during my initial answer. While I wouldn't be interested in pursuing a further formal degree at this point in my career, I would be very open to management and leadership training that I know Gilead Sciences is so well known for. I'm at the point in my career where I'm ready for that step. Other than that question, I feel confident that I've been able to portray the type of employee I would be here."

Be honest with the interviewer on how you feel the interview has gone so far. If you feel that your performance in the interview is going well, be confident as you express that fact to them. But if there was a question or two where you could have answered better, now is the time to speak up, and your interviewer will respect you for that.
