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).

BIO.5 The student will investigate and understand common mechanisms of inheritance and protein synthesis. Key concepts include
e) historical development of the structural model of DNA;
g) the structure, function, and replication of nucleic acids;
Vocabulary

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.
