Identify the central dogma of life
As you have learned, information flow in an organism takes place from DNA to RNA to protein. DNA dictates the structure of mRNA in a process known as transcription, and RNA dictates the structure of protein in a process known as translation. This is known as the Central Dogma of Life.
Does the Central Dogma always apply?
Scientists are always experimenting and exploring within their current understanding of the world. As they learn and discover new things, their ideas and understanding change to reflect the new evidence they have before them.
With modern research, it is becoming clear that some aspects of the central dogma are not entirely accurate. In order to flesh out our understanding, current research is focusing on investigating the function of non-coding RNA. Although this molecule does not follow the central dogma it still has a functional role in the cell.
