Researchers study DNA, genes

STATE COLLEGE, Pa., Nov. 25 (UPI) -- Scientists at Penn State University report learning more about some of the processes regulating genes and the evolution of the DNA regions that control genes.

The team focused on regulatory regions that, when bound to a certain protein, are thought to stimulate the genes that play a key role in developing red blood cells, the university said in a news release.

The results could help the development of drugs to treat sickle-cell anemia and other blood disorders, researchers said.
