Synthetic Biology

Definition

RNA sequencing (rna-seq) is a powerful technique used to analyze the quantity and sequences of RNA in a biological sample, enabling the study of gene expression and transcriptomics. By converting RNA into complementary DNA (cDNA) and sequencing it, researchers can identify which genes are active, the levels of their expression, and any alternative splicing events. This technique plays a crucial role in integrating various omics data into metabolic models, helping to enhance our understanding of metabolic pathways and cellular processes.
