A team of scientists studying cell division developed a special light microscopy system and used it to analyze the molecular density of cellular environments. Their results provide a novel insight ...
Team discovers transient rise in depletion attraction contributes to mitotic chromosome condensation
(A) Histone staining images and OI-DIC density imaging of human living cells in the interphase (the phase between cell divisions, left) and mitotic phase (right). The bottom two rows are OI-DIC ...
CAPTION: (Top) Condensins seem to act as a molecular crosslinkers to make loops. (Bottom, left) Condensins (red) locate around chromosome center. (Bottom, right) Nucleosomes around the periphery ...
Individual cells divide through a process called mitosis, during which the cell's copied DNA is separated between two resulting daughter cells. Despite recent advances in cell biology, the mechanism ...
In early cytological studies chromatids of metaphase chromosomes were suggested to coil into a spiral called chromonema. This assumption was recently supported by chromosomce conformation capture ...
Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from ...
(Nanowerk News) If measured from beginning to end, the DNA in our cells is too long to fit into the cell’s nucleus, explaining why it must be constantly folded and packaged. When it is time for cell ...
Researchers at the UC Davis College of Biological Sciences have discovered that a little-known protein called ATF7IP2 helps to inactivate the X and Y chromosomes during cell divisions that lead to ...
