Lesson: DNA and RNA comparison

How do the structures of DNA and RNA compare and contrast?

In biology the structure of a molecule is often directly related to its function. This lesson reviews the basic structures of nucleotides from SOL 2 and expands upon them to describe the structures of DNA and RNA (mRNA, rRNA and tRNA).

Warm Ups, etc:

DNA/RNA Chart - compare and contrast structure, sugars, bases and location

Making Copies - review the process of DNA replication using complementary base pairing and the use of each strand as a template for the copy

Activities, Assignments, Etc.

Notes - DNA Structure and Replication

Activity - Complementary Strands - students determine the order of bases that would be opposite a given strand.
