Possible Answers:

Correct answer:

Explanation:

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

Example Question #5 :Dna, Rna, And Proteins

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

Possible Answers:

DNAProteinsRNA

ProteinsRNADNA

DNARNAProteins

DNARNAEnzymesProtein

DNAEnzymesRNAprotein

Correct answer:

DNARNAProteins

Explanation:

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: DNARNAProteins

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."
