The term "junk DNA" is not used in science anymore, much of it is repetitive regions that serve regulatory functions, or other unknown reasons. "Junk" DNA has been renamed to "noncoding DNA", the recent ENCODE-project stated that 80% of human DNA has some purpose.

P.S.: That article reads like the ENCODE-project killed the term "junk DNA", however, that term wasn't in use before the release of ENCODE, either.
