Chromatin has long been proposed to "store" memory related information; but what kind of information, contents or rules does it hold?
Check out our new preprint: www.biorxiv.org/content/10.6... 1/13

Excited to share recent work from the Mischel and Chang labs in which we show functional heterogeneity arising from extrachromosomal (ecDNA) copy number heterogeneity. Preprint below! 1/13
