The Concept of Molecular Genetics

In other words, the genetic information contained in the DNA is first transcribed into RNA. This step from DNA to RNA is called transcription. Like a messenger, the RNA then carries the genetic information to the

Let us note, then, that mRNA can also be detected in higher plants and this finding helps to support the concept of molecular genetics. This mRNA is, in part, short-lived and, in part, long-lived too.
