AP: Chapter 19: Control of Eukaryotic Genome
When your AP biology class is studying DNA and genomes, this instructional activity will provide a detailed review. On the first page are diagrams and matching SEM (scanning electron microscope) images of different levels of DNA packing...

Gene to Protein
Mutation and auxotrophs are discussed. Next, the details of RNA transcription and how enzymes can control splicing and introns are given.
