Bioinformatics: Gene Expression Data and Homology Studies - Prof. Roman E. Boldyreff, Study notes of Biology

Information on bioinformatics, specifically focusing on gene expression data and homology studies. Gene expression data involves comparing the expression of several genes of a single organism in response to environmental stress, while homology studies compare nucleotide or amino acid sequences among species to determine relatedness. Fold change data and dendrograms for analyzing gene clusters and evolutionary relationships.
