Tiny genome loops persist through mitosis, reshaping our view of cell division
New insight into mitosis: small loops endure where larger structures fall away In a surprising turn for how we understand cell division, MIT researchers have found that tiny 3D loops in the genome persist—or even strengthen—during mitosis, the process by which a cell copies its DNA and divides into two daughter cells. This discovery challenges…

Tiny genome loops persist in dividing cells, reshaping mitosis understanding
Overview: A surprise in the mitotic genome For decades, scientists believed that as cells prepare to divide, their chromosomes condense into a tightly packed, featureless slate. Once division finished, the genome would gradually reestablish its complex 3D structure to regulate which genes are active in each daughter cell. A groundbreaking study from MIT challenges this…

Tiny Genome Loops Persist During Cell Division, MIT Finds
New insight into mitosis: genome structure isn’t erased For decades, scientists believed that as cells divide, the genome is stripped of its intricate 3D organization and that this structure gradually returns only after mitosis. A groundbreaking MIT study challenges that view by showing that tiny 3D loops, known as microcompartments, persist throughout cell division and…
