Transcriptomics is a branch of molecular biology that involves the study of the transcriptome, the complete set of RNA transcripts produced by the genome in a specific cell or tissue. It focuses on the analysis of gene expression patterns and RNA transcripts to understand the underlying molecular mechanisms in various biological processes. Transcriptomic research involves techniques such as RNA sequencing, microarray analysis, and quantitative PCR to measure and analyze gene expression levels, alternative splicing events, and non-coding RNA molecules. This area of research is crucial for understanding gene regulation, identifying new therapeutic targets, and predicting the functional consequences of genetic variations.
