• Unit 10: Gene Expression

    In this unit, you will learn about the universal genetic codes deoxyribonucleic acid and ribonucleic acid, which are better known as DNA and RNA. DNA and RNA are universal because one or both are found in every known organism! As you learned in Unit 7, the DNA and RNA in every organism are made up of the same few "ingredients". However, the slight differences are what account for the differences between species (what makes a dog different from a toadstool) and the differences within species (what makes you different from your neighbor). This unit will give you a greater understanding of the genetic code and its impact on your life.

    Completing this unit should take you approximately 5 hours.
