Question

gene expression quick check
which of the following demonstrates the central dogma of molecular biologists? (1 point)
proteins replicate dna which gives the expression of traits to an organism.
gene expression relies on environmental factors that determine which traits are dominant.
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.

Explanation:

The central dogma of molecular biology describes the flow of genetic information: DNA is transcribed into RNA, which is then translated into proteins, and these proteins drive gene expression and trait manifestation. The correct option aligns with this core concept, while the others describe unrelated processes (protein replicating DNA, environmental dominance, mutation effects).

Answer:

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