Reproductive cells, such as an egg and sperm, join to form stem cells that can mature into any tissue type. But how do reproductive cells arise? We humans are born with all of the reproductive cells that we will ever produce. ...

Every cell in our body has exactly the same DNA, yet every cell is different. A cell's identity is determined by the subset of genes that it activates. But how does a cell know which genes to turn off and which to turn on? ...
