“JUNK DNA” (unfortunate term) is a non-coding area of DNA which does not make proteins, and has completely unknown functions, and accounts for a whopping 97% of the human genome. The human genome sequencing was completed in 2003, but we are still ignorant about what most of it does. A 2013 report now suggests that these non-coding regions may be involved in gene regulation. ”
