Gene Expression Analysis and DNA Microarray Assays

The video tutorial explains the importance of understanding gene expression in biology, focusing on techniques like RT-PCR and DNA microarray assays. It covers how these methods help analyze gene expression in different contexts, such as embryonic development, tissue analysis, and cancer research. The tutorial highlights the process of reverse transcription to create cDNA from mRNA and the use of DNA microarrays to study genome-wide expression, providing insights into gene activity and potential mutations.
