how do cells make proteins using the message in DNA?      Phyllis Frosst, Ph.D.: I investigate genetic discrimination, direct-to-consumer marketing of genetic tests and pharmacogenomics. DNA is transcribed into an RNA message (another large nucleic acid chain) in the cell's nucleus. This message is then translated into protein by ribosomes, cellular machines that work in the cytoplasm of the cell. Fascinatingly, the molecular machines that make all of these processes happen are mostly made of protein! Shikellamy High School in PA (9th grade student)
