This volume provides comprehensive methods and protocols to detect and trace RNAs in biochemistry, molecular, cell biology, genetics, genomics of RNA biology. Chapters detail RNA labeling, RNA biology of mammalian cells, and methods on model organisms; including Zebrafish, Drosophila, C. elegans, budding yeast as well as prokaryotes including E. coli. Written for the highly successful Methods in Molecular Biology series, chapters feature introductions to their respective topics, lists of the necessary materials and reagents, step-by-step and readily reproducible laboratory protocols, and tips for troubleshooting and avoiding known pitfalls.  Authoritative and up-to-date, RNA Labeling: Methods and Protocols serves as a vital resource for researchers working in RNA labeling.
