Genetics and DNA Review
1. Watch this video clip on translation(protein synthesis): Translation clip. Draw your own pictures and
notes of what is happening.
2. Complete this practice Jeopardy game and make notes of anything you can’t answer: Genetics
Jeopardy. If you view it in Google Docs you can only scroll. The answer slide is after the question. If you
download the file it should play like a game.
