Science Writes Eulogy for Junk DNA

Elizabeth Pennisi is a science writer for Science, the premiere American science journal. She's been writing about "dark matter" for years focusing on how little we know about most of the human genome and ignoring all of the data that says it's mostly junk [see SCIENCE Questions: Why Do Humans Have So Few Genes? ].

It doesn't take much imagination to guess what Elizabeth Pennisi is going to write when she heard about the new ENCODE Data. Yep, you guessed it. She says that the ENCODE Project Writes Eulogy for Junk DNA.

THEME

Genomes & Junk DNALet's look at the opening paragraph in her "eulogy."

When researchers first sequenced the human genome, they were astonished by how few traditional genes encoding proteins were scattered along those 3 billion DNA bases. Instead of the expected 100,000 or more genes, the initial analyses found about 35,000 and that number has since been whittled down to about 21,000. In between were megabases of “junk,” or so it seemed.
