Molecular Biology

Articles in Molecular Biology, the branch of science devoted to studies of the structure, function, and reactions of biomolecules involved in the life processes. It is chiefly concerned with the understanding the interrelationship of DNA, RNA and protein synthesis and learning how these interactions are regulated.

Jefferson Scientists Show “Dachshund” Gene Reverts Cancer Genes to Normal, Predicts Breast Cancer Prognosis
Scientists have shown that the activity of a gene that commandeers other cancer-causing genes, returning them to normal, can predict the prognosis of an individual with breast cancer.
