Human, Cow, And Snorks Ws

Welcome to the electronic frontier of the 21st century science classroom. This testing instrument is based upon electronic worksheets taken from the web site; (1) Transcription and Translation worksheet, (2) How DNA controls the Workings of the Cell, (3) and (4) DNA, RNA, and Snorks. Good Luck with your test. (Please note when entering triple codons for DNA and RNA, make sure you enter them as capital letters. )
