Abstract
The frequency occurences of K-tuple (overlapping sequences of defined length, K) were computed from the known human genome sequences. The significance of these frequencies for the whole human genome was tested by polymerase chain reaction (PCR). A computer program based on these results was written to choose primers to amplify DNA target sequences, either of human genes or of human infectious agents. The software also gave nested primer sequences which were used to synthesize non radioactive probes by PCR. We applied these two methods, primer selection and non radioactive probes, to easily and quickly set up very efficient PCR sets to work in the human genome context.
