CDCA7's Role in DNA Methylation Maintenance Revealed in Recent Study

DNA methylation is a process in which a methyl group is attached to the cytosine base of the DNA molecule, and a major way that DNA is epigenetically marked. Epigenetic modifications can act as on-off switches to regulate gene expression and help generate diverse cell types without changing the underlying DNA sequence. It is how the body ensures that brain-related genes don't get turned on in heart cells, for example.

Computational Modeling and Experimental Findings on Nucleosome Constraining in Mitosis

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 by which DNA condenses during mitosis is still poorly understood. Researchers recently tracked small stretches of DNA wound around histone proteins, called nucleosomes, to better characterize nucleosome behavior during cell division.
