Examination of eight Atlantic species of the genus Littorina by starch gel electrophoresis of purine nucleoside phosphorylase revealed extensive polymorphism within the L. saxatilis complex. In this group, four alleles have been identified. Heterozygotes are four banded, and thus, as in vertebrates,
The molecular basis of four electrophoretic and activity variants of purine nucleoside phosphorylase in the mouse was examined by amplification and sequence analysis of cDNA. Compared with the cDNA coding sequence for C3H/HeHa designated Np a, there were five nucleotide changes for C57BL/6J, Npb; th
