Microarray Techniques and RNA Seq by Dr. K - University of Zambia - Biomedical Sciences-unza

Description

This presentation note outlines the principles, applications, and comparison of microarray techniques and RNA sequencing as advanced biotechnological tools for genomic analysis. It details how DNA microarrays operate on the principle of hybridization between immobilized probes and complementary target sequences from samples, used for high-throughput gene expression profiling and genotyping, with applications in disease diagnosis and pharmacogenomics. The material also explains RNA-seq as a next-generation sequencing technology that converts RNA to cDNA for sequencing, enabling comprehensive transcriptome analysis, detection of novel transcripts, alternative splicing, and non-coding RNAs, with types including bulk and single-cell RNA-seq. Authored by Dr. K from the Department of Biomedical Sciences at the University of Zambia, this resource is designed for tertiary students in biomedical sciences and related programs, providing essential revision material on modern molecular techniques for exam preparation and research understanding. The notes compare the advantages and limitations of both methods, such as microarray cost-effectiveness versus RNA-seq's sensitivity and discovery potential, serving as valuable university notes for mastering genomic data generation and analysis in Zambia. Review this guide to understand the technical foundations and appropriate applications of these pivotal tools in contemporary biological research.
