Unraveling Oxytricha Trifallax’s Mysterious Genome: 15,600 Chromosomes and Counting

You have 46 chromosomes. This Pond Creature has 15,600 Chromosomes

O.o probs alien o.o circa 2013.

Remember when encyclopaedias used to be books and not only websites? You would have a whole shelf of information that was packaged into individual entries and then separate volumes. In a similar fashion, your genome is organized. Your DNA is arranged into large volumes known as chromosomes. Each pair contains a long sequence of genes. Telomeres are protective structures that protect your chromosomes, just like encyclopaedias are protected by sturdy covers.

This is how it works for any animal, plant or fungus. Fruit flies may have eight chromosomes, while dogs have up to 78. But the basic structure is the same.

Oxytricha Trifallax is a creature that lives in ponds. Its DNA is organized very differently. The genome of the pond-dwelling creature Oxytricha trifallax was sequenced for the first time by a team of US scientists, who discovered genetic chaos. It looks like someone tore out the pages of encyclopedias, tore some of them and photocopied the entire thing dozens of time.
