The “Card Images” ZIP file contains individual image files for the cards used in this activity that can be used in the classroom, particularly in online courses. Having too many chromosomes can lead to too much gene expression. However, we found that it is possible to achieve cell-type specificity if expression is limited to the overlap in the expression patterns of two Generation 1 lines. They are degraded by proteasomes. The gene expression program underlying the specification of human cell types is of fundamental interest. It is difficult to develop genetic therapies for diseases caused by variations or mutations in many genes (multigene diseases). Tools are provided to help users query and download experiments and curated gene expression profiles. Predict possible intervention strategies for different genetic conditions.
