Emerging role of dynamic RNA modifications during animal development.

The central dogma of molecular biology statically says that the information flows from DNA to messenger RNA to protein. But the recent advances in mass spectrometry and high throughput technology have helped the scientists to view RNA as little more than a courier of genetic information encoded in the DNA. The dynamics of RNA modifications in coding and non-coding RNAs are just emerging as a carrier of non-genetic information, uncovering a new layer of complexity in the regulation of gene expression and protein translation.
