Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The central dogma of biology states that information flows in one direction from
A
nuclei to RNA to cytoplasm
B
ribosomes to proteins to DNA
C
genes to nuclei to ribosomes
D
DNA to RNA to proteins
Explanation: 

Detailed explanation-1: -The central dogma of molecular biology is a theory stating that genetic information flows only in one direction, from DNA, to RNA, to protein, or RNA directly to protein.

Detailed explanation-2: -Summary. The central dogma of molecular biology states that DNA contains instructions for making a protein, which are copied by RNA. RNA then uses the instructions to make a protein. In short: DNA → RNA → Protein, or DNA to RNA to Protein.

Detailed explanation-3: -Thus, during expression of a protein-coding gene, information flows from DNA → RNA → protein. This directional flow of information is known as the central dogma of molecular biology.

Detailed explanation-4: -Transcription is the process by which the information is transferred from one strand of the DNA to RNA by the enzyme RNA Polymerase.

Detailed explanation-5: -The classic view of the central dogma of biology states that “the coded genetic information hard-wired into DNA is transcribed into individual transportable cassettes, composed of messenger RNA (mRNA); each mRNA cassette contains the program for synthesis of a particular protein (or small number of proteins)."
