ABSTRACT
RNA, ribonucleic acid, is a key biological molecule and in bacteria it is responsible for a variety of functions within the cell. The RNA from bacterial cells has been investigated using a variety of techniques, starting from the simple isolation of the nucleic acids away from the other components of the cell to understanding the sequence order of the ribonucleotides. Each of the types of RNA (mRNA, tRNA, rRNA, and ncRNA) has differences in their lengths, compositions, functions, and structures. These differences will be explored in this chapter, demonstrating how various RNAs contribute to the regulation of gene expression.
