Quiz #1

Chapter 3: The Cell

True or False

1.)   Ribosomal subunits are produced in the cytoplasm

    Is there any way you can you please post the answers? I know we discussed it in class yesterday, but I think I missed when we went over a couple.

      Done! It is in the practice quiz section. If you want one of the questions explained again just ask.

    Will the tests consist of questions like these, or will the tests consist of more complex/harder questions?

    I think they will be pretty similair, if anything the test questions may be a tad simpler. They will still make you think, but I think it is safe to say that everyone who has read the material and understood the quizzes, practice and in class, will do really well on the tests.
