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

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.
