1. DNA replication, transcription, the genetic code, and translation

2. DNA function 1. replication

3. Backbone does not vary within or between DNA molecules So backbone can be represented by a straight line Replication: Each of the 2 replicated molecules have 1 parent strand (old) and 1 daughter strand (new) Complementary base pairing

4. DNA function 1. Protein synthesis Structure Basic building block: amino acids 20 A.A. A protein

6. Protein synthesis Transcription Translation

8. mRNA processing
