Question

which of the following best summarizes the flow of genetic information in cells?\
dna → protein → rna\
rna → dna → protein\
rna → protein → dna\
dna → rna → protein

Explanation:

This refers to the central dogma of molecular biology, which describes the standard flow of genetic information in most cells: DNA is transcribed into RNA, and RNA is translated into protein. Reverse flow (RNA to DNA) occurs only in specific organisms like retroviruses, not as the general cellular flow.

Answer:

DNA → RNA → protein
