Abstract excerpt
We have systematically varied microsatellite sequence composition to determine the effects of repeat unit size, G+C content, and DNA secondary structure on microsatellite stability in human cells. The microsatellites were inserted in frame within the 5' region of the herpes simplex virus thymidine kinase (HSV-tk) gene. The polypyrimidine/polypurine microsatellites displayed enhanced S1 nuclease sensitivity in...
