DNA MAKES RNA MAKES PROTEIN

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is the correct order of information transfer in a living organism?
A
DNA to RNA to Protein
B
protein to DNA to RNA
C
RNA to DNA to protein
D
RNA to protein to DNA
Explanation: 

Detailed explanation-1: -In order for a cell to manufacture these proteins, specific genes within its DNA must first be transcribed into molecules of mRNA; then, these transcripts must be translated into chains of amino acids, which later fold into fully functional proteins.

Detailed explanation-2: -The process by which DNA is copied to RNA is called transcription, and that by which RNA is used to produce proteins is called translation.

Detailed explanation-3: -In the first step, the information in DNA is transferred to a messenger RNA (mRNA) molecule by way of a process called transcription.

Detailed explanation-4: -The central dogma of molecular biology states that information flows from DNA (genes) to mRNA through the process of transcription, and then to proteins through the process of translation.

Detailed explanation-5: -The central dogma states that the pattern of information that occurs most frequently in our cells is: From existing DNA to make new DNA (DNA replication?) From DNA to make new RNA (transcription) From RNA to make new proteins (translation).
