Lesson 22 – DNA and RNA

Lesson Description

In this lesson, students focus on the nucleotide polymers DNA and RNA. We explore the structure of messenger RNA and transfer RNA, as well as the ribosome, a massive molecular factory that reads messenger RNAs and translate their sequences into protein. We also explore life’s genetic code, and students learn how to read a gene. We conclude by investigating the structure of DNA, and set the stage for an understanding of DNA replication and transcription.
