We've now zoomed in enough to see portions of the DNA strand. The DNA is wrapped around histones -- protein structures that are sometimes depicted as discs. Histones carry a slight positive charge ...

Males, with their single X chromosome ... This stalled meiotic progression coincided with the activation of a DNA damage checkpoint, triggered by double-strand break formation, leading to defects like ...

each A in one strand always pairs with a T in the other strand, and each C always pairs with a G. The double-stranded DNA that results from this pattern of bonding looks much like a ladder with ...

There are four different bases in DNA: Base pairs on a section of DNA The order of the bases along a strand of DNA is a ... match and are called autosomes In males the sex chromosome pair is ...

In a study published in Nature, researchers report the successful in vitro reconstitution of meiotic DNA double-strand breaks (DSBs) formation. Meiosis, a specialized form of cell division in most ...
