How chromosomes find their partners
In fruit flies, specific repetitive DNA sequences enable matching chromosomes to find one another during meiosis and pair up. Each pair of chromosomes carries a characteristic repeat pattern that functions like a molecular barcode. Different species contain distinct repeat barcodes, suggesting that this finding may also yield insights into how new species arise.

Scientists found that DNA once dismissed as “junk” helps chromosomes find their partners
For years, the dense loops of repetitive DNA clustered near the middle of chromosomes were treated as evolutionary clutter. According to the new study published in Nature, titled…
