Cellular Control Systems

Grade Level

12th Grade (Senior High School)

Duration

60 minutes

Class Size

1 student (individualized instruction)

Lesson Overview

This lesson concentrates on the structure and function of cellular control systems with a focus on genetic information flow (DNA to RNA to protein), the pH scale, and the cardiac conduction system as applicable to physiology and molecular genetics. These topics closely align with the Science portion of the ATI TEAS Version 7 exam and are mapped to the Common Core State Standards (CCSS) for Science and Technical Subjects as well as the Next Generation Science Standards (NGSS).
