Totipotency is the ability of a cell to develop into an individual through elaborate processes of embryogenesis and is created during the development of the precursors of sperm and eggs, which are called germline cells. Understanding ...

Higher water temperatures induce specific chemical tags at targeted locations on the DNA of embryonic zebrafish. These "epigenetic" changes can then reroute genetic pathways, so that the embryos change sex. This finding, ...

One way cells can control the activities of their genes is by adding small chemical modifications to the DNA that determine which genes are turned on or off. Methyl groups are one of these chemical modifications or tags. ...

All the cells in an individual's body bear the same genetic code. It is the reading and writing of this code—the "turning on" and "turning off" of specific genes in specific cells—that gives the cells their identities. ...
