Question

what is the flow of the central dogma? it flows from rna, to dna, and then to trna. it flows from dna, to mrna, and then to proteins. it only flows into dna.

Explanation:

The central dogma of molecular biology describes the flow of genetic information. It states that DNA is transcribed into mRNA (messenger RNA), and then mRNA is translated into proteins. The first option is incorrect as the flow isn't from RNA to DNA to tRNA. The third option is incorrect as the flow isn't only into DNA. The second option correctly states the flow from DNA to mRNA to proteins.

Answer:

B. It flows from DNA, to mRNA, and then to proteins.
