1. What is the structure of DNA?
DNA = deoxyribonucleic acid
Linear polymer of 4 sub-units (nucleotides)
2. What is the 4 characteristics of DNA?
(1) DNA strands consist of subunits called nucleotides
(2) DNA is a linear polymer of nucleotides linked by phosphodiester bonds
(3) Cellular DNA molecules take form of double helix
(4) 3D structure of DNA gave important clues about its function
3. What is Chargaff’s Rule?

Document Summary
Nucleic acids and encoding biological information - Assigned readings in textbook complete before lecture 4: Chapter 2 (section 2. 5) organic molecules- nucleic acids (pages 40 to 42) Chapter 3 (section 3. 1) major biological functions of dna (pages 50 to 53) Chapter 3 (section 3. 2) chemical composition and structure of dna (pages 53 to 58) Use the following wireframe outline to make notes on the content presented in lecture 4. Chargaff"s rule states that the number of a bases must equal the number of t bases and the number of g baes must equal the number of c bases. Dna is the genetic material in all organisms. The structure of rna and dna allow them to make their molecules more stable, compact and allows them to carry information needed to make proteins or other information. Their structures both also allow them to store large amount of information.
