Example Questions

Example Question #6 : Dna, Rna, And Proteins

Which of the following depicts the central dogma of molecular biology?

Possible Answers:

Correct answer:


The central dogma of molecular biology states that DNA is transcribed into RNA, which is then translated into protein.

Example Question #7 : Dna, Rna, And Proteins

Which one of the following lists the steps of the central dogma in the correct order?

Possible Answers:

DNA  Enzymes  RNA  protein

DNA  RNA  Proteins

DNA RNA Enzymes  Protein

DNA  Proteins  RNA

Proteins  RNA  DNA

Correct answer:

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."
