RNA biology is a branch of molecular biology that focuses on the study of RNA molecules and their functions within cells. This includes the processes of RNA transcription, RNA processing, RNA modification, and RNA transport. RNA molecules play crucial roles in gene expression, regulation of gene activity, and protein synthesis within cells. Research in RNA biology seeks to understand the structure, function, and regulation of different types of RNA molecules, as well as their interactions with proteins and other cellular components. This field has led to important insights into various biological processes, disease mechanisms, and potential therapeutic interventions.
