Question

Which of the following demonstrates the central dogma of molecular biologists?(1 point)
Responses

DNA and RNA mutate into either harmful or helpful effects on the human body.
DNA and RNA mutate into either harmful or helpful effects on the human body.

DNA and RNA hold the code to create proteins that are the key to gene expression.
DNA and RNA hold the code to create proteins that are the key to gene expression.

Proteins replicate DNA which gives the expression of traits to an organism.
Proteins replicate DNA which gives the expression of traits to an organism.

Gene expression relies on environmental factors that determine which traits are dominant.

Answer 1

"DNA and RNA hold the code to create proteins that are the key to gene expression."

Reason: the central dogma describes information flow from DNA to RNA (transcription) and from RNA to protein (translation). The other choices misstate the direction of information flow or confuse gene expression with environmental effects.
