This reading guide was made for Openstax Ch 15, which covers genes and proteins. Some of the text is more detailed than what I cover in AP Biology, but the reading guide allows students to skim and pick out the important sections. Students learn how DNA is transcribed into mRNA which is that used to build a protein during the process of translation. Other details are covered, such as the Poly-A tail and the TATA box.
The student worksheet is available for free at biologycorner.com.
