Chromatin structure is highly complex and impressively ... more directly with DNA and the different proteins within the nucleus. Because eukaryotic DNA is tightly wrapped around nucleosomes ...

5 Chromatin segments found at loop junctions are in such close ... One hypothesis is that the DNA loops could determine which genes are switched on in the cell. Inside a nucleus, chromosomes jumble ...

the bundle of DNA and proteins that form chromosomes within the nucleus of cells. The scientists observed that chromatin self-organizes into "packing domains"—distinct, compact regions of ...

In humans and other multicellular organisms, cells multiply. This defining feature allows embryos to grow into adulthood, and ...

To fit such a long molecule within the tiny space of the nucleus, DNA bends and loops in several ways. The largest of these loops results from the helical coiling of chromatin (the thick line in ...

The shape and mechanics of the nucleus are known to be influenced by internal factors, such as the organization of chromatin (the structure containing DNA) and the nuclear lamina (a network of ...

p53 enhances DNA repair and suppresses cytoplasmic chromatin fragments and inflammation in senescent cells - ...

Researchers have discovered a cellular mechanism that helps nocturnal mammals see in the dark. Mice, cats, deer, lemurs, and other mammals that are active at night remodel the DNA within their eyes to ...

2. The resting nucleus consists of delicate chromatin threads or meshes, with some nodelike structures at the intersections of the threads. 3. The first indication that reduction is about to take ...

Yeast also has the same way of organizing chromosomes, while in humans and other mammals, each chromosome occupies its own specific region in the nucleus. "If we look at the average chromatin ...
