'Genetic network' guards against lethal DNA damage
...ay to identify which of the sensors found matching barcodes that identified specific yeast cells with specific mutations. If two genes that compensated for each other are knocked out, the yeast cell dies and the microarray doesn't record that cell, Boeke noted. That means the two genes interact with each othe......anner that is analogous to a laser scanner reading barcodes on itemsin the grocery store. In this case the inventory isn’t cans of food butthe database of the human, mouse, or rat genome sequences. And becausethe scientists know that each of these tags lies within, at most, 500to 1,500 bases of a CREB-binding...
