mistake on grad school application

[AaniaS]

Hi,

I made a mistake in my grad school application, where I clicked 'no' to the question 'do you have undergraduate research experience' when the answer is actually 'yes'. However, my CV and transcripts do show my undergrad research coursework which are uploaded onto the application, plus I also have research experience from Masters and job. Should I email the admissions committee with this correction or is it small enough to be ignored? Also, is this something that will affect my application? This was one of my top schools so kind of bummed out.
