How does computer codon optimization enhance gene synthesis projects?

General Biosystems codon optimization tool has the ability to optimize multiple critical parameters to stabilize DNA fragments and improve gene expression efficiency. Parameters include but not limited to:
(1) Codon Usage Bias;
(2) GC content;
(3) mRNA Secondary Structure;
(4) Custom Desired Patterns;
(5) Custom Undesired Patterns;
(6) Repeat Sequences (direct repeat, inverted repeat, and dyad repeat);
(7) Restriction Enzyme Recognition Sites (deletion or insertion).
