Answer:
B. The production of proteins based on the genetic information in DNA
Explanation:
Gene expression is the set of processes by which information contained in genes is converted into molecules that determine cell properties, that is, the transfer of genetic information from DNA to protein.
The expression of a gene encompasses a series of steps ranging from the synthesis of an RNA molecule, from a base sequence in the DNA molecule (gene) to the synthesis of a protein from that RNA molecule (messenger RNA).
