While all human chromosomes contain repeats, more than 30 million letters of the Y chromosome — out of 62.5 million — are repetitive sequences, sometimes called satellite DNA or junk DNA.

The type of repetitive DNA contributing most to cancer detection was the largest subfamily of Alu elements, called AluS; the blood plasma of people with cancer had less of it than usual.

Though small, the Y chromosome has intimidated many researchers because it has so many repetitive bits of DNA, says Adam Phillippy, a bioinformatics researcher at the U.S. National Human Genome ...

The rest are nonfunctional repetitive sequences long deemed “junk DNA,” though scientists now know that it’s not actually junk. A lot of that genetic gibberish can affect how genes function.
