DNA, RNA and Protein Synthesis Activity Part 2

Introduction

This activity illustrates how the order of nucleotides in DNA determines the order of amino acids in proteins. It reinforces the concept that any change in the order of nucleotides can change the order of amino acids in proteins.

This second part of the activity will allow you to learn the basics about nucleic acids, how they form base pairs, and undergo replication and translation, as well as the methods and findings of some of the classic experiments in this area. By using a computer website, follow all directions and read all the required information to reinforce your understanding of DNA and protein synthesis.

Be sure to go at a comfortable rate; however, follow all directions

and read all the required information.
