How Much Do You Know About The Central Dogma Of Molecular Biology? - Quiz

The central dogma of molecular biology can be defined as an explanation of the flow of genetic information within a biological system, which was introduced in 1958 by Francis Crick. The main argument behind Crick's statement is that "once information has passed into protein it cannot get out again.
