A new study suggests that so called “junk DNA” might be what separates apes and man
For decades, people referred to the non-coding bits of DNA between genes as junk DNA. Then, in the eighties scientists discovered that some of that junk DNA served an important purpose. The DNA attracted or repelled transcription factors and RNA, greatly enhancing or inhibiting the potency of adjacent genes. Now scientists have just found that one of those gene enhancers may be what separates humans and chimps.
