Graduate Concentration in Molecular Biology and Genetics: Comprehensive Exam Guidelines

Image Picker for Section 0

Good sources for review of these topics are:

  1. Molecular Biology of the Cell by Alberts et al. or Molecular Cell Biology by Lodish et al. (Textbooks used for BISC 401)
  2. Genetics: From Genes to Genomes LH Hartwell, L Hood, ML Goldberg, AE Reynolds, LM Silver, RC Veres (Textbook for BISC 403)
