The central dogma of molecule genetics states that the genetic information flows

Answer»

Amino acids `rarr` Proteins `rarr DNA`
`DNA rarr` Carbohydrates `rarr` Proteins
`DNA rarr RNA rarr `Proteins
`DNA rarr RNA rarr` Carbohydrates

Solution :The FOLLOWING concepts constitute the central dogma of molecular genetics:
(a) `DNA` molecules can synthesize other `DNA` molecular idential with the original (Replication).
(b) A single strand of `DNA` can act as a TEMPLATE on which a molecule of `RNA` is synthesized in a specific manner (Transcription)
(C ) `RNA` molecules in turn directs the synthesis of specific proteins which are charactersitic of each kind of organism (Translation).
They were summarized by Franicis CRICK as follows:
`DNA overset("Replication")rarr DNA overset(overset("Transcription")rarr)underset("REVERSE transcription")larr RNA overset("Translation")rarr "Protein"`
