How to Analyze RNAseq Data for Absolute Beginners Part 15: A Complete Guide to miRNA-seq Analysis
Understanding the World of microRNAs The fascinating world of microRNAs (miRNAs) represents one of molecular biology’s most elegant regulatory systems. These tiny RNA molecules, spanning just 20-24 nucleotides, function as precise genetic regulators by binding to messenger RNAs (mRNAs) and fine-tuning their expression. Since their serendipitous discovery in the early 1990s, miRNAs have revolutionized our

How to Analyze RNAseq Data for Absolute Beginners Part 13: Circular RNAseq Analysis
Understanding the Biology of Circular RNAs The Nature of Circular RNAs Circular RNAs (circRNAs) represent one of molecular biology’s most fascinating discoveries. Unlike the linear RNA molecules that dominated our understanding of gene expression for decades, circRNAs form continuous loops through a unique process called back-splicing. In this process, a downstream 5′ splice site connects
