"The DNA of an organism can be viewed as its hard drive, containing programs and other information needed to run the cell.
Copies of programs in the DNA, called genes, are transcribed into RNA much like programs from a computer hard drive are copied into temporary memory so the software can be readily used.
Scientists initially thought that the information coded into RNAs didn’t change—it was either used to make a protein, or the RNAs were used directly for some specific purpose in the cell. However, it turns out that the bases in the RNA can be changed dynamically on the fly in a fine-tuning process called RNA editing.
A common type of RNA editing involves the alteration of an adenosine base to an inosine base (A-to-I editing). The inosine base is not part of the standard genetic code, but is interpreted as a guanine base by the cellular machinery. This type of editing has profound effects on gene expression and can lead to the creation of different forms of proteins or RNAs with different functions. Its purposes are still being discovered, but it’s known to be involved in the adaptation and function of the nervous system where lightning-quick responses are required." ICR
