Moving Genes and Quiet Revolutions: Barbara McClintock and Transposable Elements

Jumping genes are changing polar bear genomes… for the better? 🐻‍❄️🤔 New research shows a subpopulation of polar bear in Southern Greenland has increased activation of transposable elements (jumping genes) compared to northern living bears that is caused by their warmer environment 🥵 Could this subpopulation be an emerging species of polar bear that will withstand the habitat destruction caused by climate change? 🌎 Only time will tell 🗓️ #science #polarbear #genetics #STEM #evolution

Not all of your DNA just sits there. Some of it can move.. and it has changed evolution! Transposable elements sound chaotic, but they’re a huge part of how genomes actually work 🧬 Head to my profile for part 2.. how this leads to the placenta. _____ Citations: Ayarpadikannan, S., & Kim, H.-S.
