(Phys.org) —A team of researchers at Florida State University has found an epigenetic factor involved in voles' lifelong pair bonding. In their paper published in the journal Nature Neuroscience, the researchers describe ...
The tight wrapping of genomic DNA around nucleosomes in the cell nucleus makes it unavailable for gene expression. A team of Ludwig-Maximilians-Universitaet (LMU) in Munich now describes a mechanism that allows chromosomal ...
