Doubt it. When you input your courses in the online application you write out the name of the course as well as the abbreviation. So I am guessing your title will say "Teachers Assistant : Biology X". Also they get a copy of your Transcript so I am sure they will connect the dots.
You can label any course as whatever you want, but they go over it and change anything they dont agree with. If there is a real discrepancy then you can email them the course website and they will look at the syllabus.
