Overall, the authors obtained sequence for 93 percent of the genome areas they targeted with their DNA chip.
The pattern of gene activity can be quickly read by DNA chips.
To learn more about the genes' where and why, they created a "DNA chip" with samples of the 5,000 genes.
Typically, testing is done using a DNA chip that is designed to identify common variations in the human genome, like single base pair differences.
To provide an accurate genotyping, however, a DNA chip must contain thousands of individual variants.
Its first DNA chips are now being put through their paces by pharmaceutical companies and academic biologists.
The DNA chips are built on a similar principle and with the same masks and alignment machines used in semiconductor factories.
The key will be a DNA chip.
And by that time, labs expect to have DNA chips capable of reading hundreds or even thousands of genes simultaneously from a single embryo cell.
A protein chip requires a lot more steps in its creation than does a DNA chip.
