Diversity and complexity of HIV-1 drug resistance: a bioinformatics approach to predicting phenotype from genotype.

abstract：:The human renin gene was isolated from a Charon 4A human genomic library and characterized. The gene spans about 11.7 kilobases and consists of 10 exons and 9 introns that map at points that could be variable surface loops of the enzyme. The complete coding regions, the 5'- and 3'-flanking regions, and the exon-intron...
