25 Questions

1. A site - incoming aminoacyl tRNA - Psite accomodates growing Peptide - E site holds EmplytRNA as it exits

2. Bm - kidney - ears and eyes

3. Rampant - Massive - TIny rRNA is most common - then mRNA and then tRNA

4. Prophas - metaphase - anaphase telophase

5. Tansport cellular cargo toward opposite ends of microtubule tracks
