Transcription and Translation PRACTICE Exam
Biology B/Transcription and Translation
Directions:
1. Put your name on this test packet.
2. Answer all questions directly onto this test packet.
3. Take this test as though it were the real exam:
a. Set aside one hour in a quiet place to take the test.
b. Attempt to answer all questions WITHOUT using notes or your book.
c. After attempting to answer all questions on your own, go back to your notes and book to find answers
to the questions you could not answer. Mark which questions these were so that you can return to
these as you continue to study.
d. You will correct your own test in class, so that you can evaluate how much more you need to study. I
will give you a score out of 10 points for my grade book, based on whether or not you completed the
test.
4. The questions on this test are NOT identical to the questions on the real test. They cover similar information
and are a similar level of difficulty.
