Example Questions
Example Question #1 : The Central Dogma
Which of the following depicts the central dogma of molecular biology?
The central dogma of molecular biology states that DNA is transcribed into RNA, which is then translated into protein.
Example Question #8 : Dna, Rna, And Proteins
Which one of the following lists the steps of the central dogma in the correct order?
DNA RNA
Enzymes
Protein
Proteins RNA

RNA
DNA RNA
Proteins
The central dogma describes the flow of information from genes to a final protein. Initially, information is coded within DNA. During transcription, this information is transferred to RNA molecules. The RNA molecules are then transcribed to create functional proteins.
The correct sequence is: DNA RNA
Proteins
Note that enzymes are a particular type of protein. Though enzymes can help with transcription and translation, they are not considered an independent step in the central dogma and fall under the more general category of "proteins."
