Method for identification of origins of replication and genes
... All organisms face the problem of DNA replication, which happens once every cell cycle before cell division. DNA replication must be under strict control with respect to cell division or else daughter cells will either lack DNA or have too much DNA. In mammals, loss of control over the cell cycle DN ...
