Methods and apparatus for preparing arrays comprising features having degenerate biopolymers
First Claim
1. A method for synthesizing a plurality of biopolymers comprising nucleotides at predetermined feature locations on a surface of a substrate wherein a feature location of said feature locations comprises degenerate biopolymers comprising nucleotides, said method comprising:
- producing a mixture of two or more different biopolymer subunit precursors; and
providing said mixture to a predetermined feature location on said surface of said substrate in a round of multiple rounds of subunit additions to produce the feature location comprising degenerate biopolymers.

Abstract
Methods and apparatus are disclosed for synthesizing a plurality of biopolymers at predetermined feature locations on a surface of a substrate. One or more of the feature locations comprises degenerate biopolymers. One or more biopolymer subunit precursors are added, in multiple rounds of subunit additions, at each of multiple feature locations on the surface to form the plurality of biopolymers on the surface. For each feature location comprising degenerate biopolymers, the biopolymer subunit precursors comprise a mixture of biopolymer subunit precursors for forming the degenerate biopolymers at the feature location.
