Base compositions of the PCR amplicons generated using primer pairs VIR982, VIR985, VIR979, and VIR988.

Abstract

<p>Within each column, identical base compositions for different isolates for a particular primer pair are shown grouped by the same color. DNP (did not prime) indicates that a PCR amplicon was not generated using the specified primer pair and viral DNA. The numbers in the columns under the primer pair ID indicates the numbers of each base (A, G, C, and T) in the PCR amplicons generated from the target virus. Signature source indicates whether the base composition signatures were determined from sequence or experimentally using viral genomic DNA.</p
