      Hello , I m confused by the plethora of information about Humane Genes online, Some say there is a difference between Non-Coding DNA and Junk DNA, some say there is NOT. I read it in rationalwiki Non-coding DNA” refers to portions of the genome that don’t code for proteins, the Rest are Junk. As it says – 

      quote :

      “Non-coding DNA” refers to portions of the genome that don’t code for proteins…Protein-coding and non-coding DNA (known functional DNA) make up about 8.7% of the human genome, and 65% of the rest is known junk. It is assumed that the unknown 26.3% is most likely junk — geneticists and ENCODE project members differ in that ENCODE tends to assume functionality as a null hypothesis (ironically, so do creationists) and real scientists assume non-functionality.”

      what about Pseudogenes and JUNK RNA, are they Non-Coding or Junk ? Someone pls clarify these thing in layman term.
