Abstract:
Dosage compensation modulates global expression of an X chromosome and is necessary to restore the balance between X-chromosome and autosome expression in both sexes. A central question in the field is how this regulation is directed. Large non-coding RNAs, such as Xist in mammals and roX in flies, have pivotal roles in targeting chromosome-wide modification for dosage compensation. Several recent studies in Drosophila provide new insight into the principles of X-chromosome recognition and the function of non-coding RNA in this process.

Types of RNA
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in the regulation of gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.
