1. Molecular Genetics [C2]
Unit 5. Molecular Genetics (15 days)
Textbook Readings
Chapters 16, 17, 18, 19, 20
Essential Knowledge
2.E.1 Timing and coordination of specific events are necessary for the normal development of an
organism, and these events are regulated by a variety of mechanisms
3.A.1 DNA, and in some cases RNA, is the primary source of heritable information
3.B.1 Gene regulation results in differential gene expression, leading to cell specialization
3.B.2A variety of intercellular and intracellular signal transmissions mediate gene expression.
3.C.1 Changes in genotype can result in changes in phenotype
3.C.3 Viral replication results in genetic variation, and ciral infection can introduce genetic
variation into the hosts
4.A.3 Interactions between external stimuli and regulated gene expression result in specialization
of cells, tissues, and organs
Laboratory Exercises
AP® Biology Laboratory 6: Molecular Biology [C8]
o Goal: To understand bacterial transformation, prepare competent E.coli cells, to transfer
genes using a plasmid, to cut DNA using restriction endonucleases, to use gel
electrophoresis to separate DNA fragments for later analysis (wet lab)
