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.

Cryo-EM Reveals CDCA7's Hemimethylation Sensing in Nucleosome Core Particles

DNA methylation, a process by which methyl groups are added to DNA molecules, is essential for the maintenance of DNA and the overall health of an organism. Disruptions in the standard DNA methylation patterns can lead to immunodeficiency and diseases such as cancer.

Multiciliated Cell Differentiation Regulated by an Alternative Cell Cycle

A fertilized egg can develop into a baby through the amazing process of cell division, while a malignant cell can become a malignant tumor. Since there is so much on the line, nature maintains strict control over it through a mechanism known as the cell cycle that scientists once believed they thoroughly understood.

Researchers Identify Molecular Stop Signal in Cell Division Monitoring

Every second, many million cells divide throughout the body. During nuclear division (mitosis), the genetic material must be divided correctly and fully amongst daughter cells; faults in this process can result in improper development or genetic diseases, and many cancer cells have an uneven number of chromosomes.
