Making GeneChips™ at Affymetrix
Description:
A technician prepares to load a filter mask into the photolithography camera. These filters allow the technician to build customized chains of DNA. The blue boxes on the right store 50-100 filters needed to produce a single type of GeneChip™.

- Marshall Nirenberg and Heinrich Matthaei used poly-U mRNA in a cell-free system to make a polyphenylalanine protein chain. This showed that UUU must be the code that specifies the amino acid phenylalanine.
