Lesson 22 – DNA and RNA
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.
