...eing synthesized, the APOBEC proteins mutate it by changing one of DNA's four bases--cytosine--to another base, uracil. But the DNA must be further copied to become double-stranded in order to insert itself into the human genome. The DNA appears to do this without incident, copying the mutations along with th...'Mighty mouse' gene works the same way in people
...d only to create protein-making instructions, thus changing the gene's protein-building message. "The mutation caused the gene's message, the messenger RNA, to be wrong," says Hopkins neurologist Kathryn Wagner, M.D., Ph.D., who tested the genetic mutation's effect in laboratory studies. "If the message had ...Energy conservation targets hit by notions of 'comfort'
