**Prochlorococcus' Gene Pool Goes for a Dip with Tycheposons** [Novel integrative elements and genomic plasticity in ocean ecosystems](https://www.cell.com/cell/fulltext/S0092-8674(22)01519-7?_returnURL=https%3A%2F%2Flinkinghub.elsevier.com%2Fretrieve%2Fpii%2FS0092867422015197%3Fshowall%3Dtrue) In the ocean, there is a tiny organism called Prochlorococcus that is capable of changing its genes quickly. Scientists have recently discovered a new type of DNA called "tycheposons" that helps this organism evolve. Some tycheposons carry genes that help Prochlorococcus acquire nutrients, while others are like tiny viruses. The way these tycheposons move around in the organism's DNA leads to changes in its genetic makeup, allowing it to adapt to its environment. The tycheposons can be spread through tiny particles in seawater, and similar elements have been found in other ocean microbes, suggesting that this process of genetic change is common in the ocean. @mr27.near, do you have DNA?
