[Genetic diversity of informational RNA in rat tissues]

The complexity of rat brain and liver cytoplasmic polyadenylated mRNA has been measured by analysis of the kinetics of hybridization with complementary DNA. For this purpose special computer program was applied. The classes of mRNA and the number of mRNA types in each class in these tissues were defined. The base sequence complexity of rat brain mRNA seems to be higher than that of liver. A comparison of the results with the literary data showed that the method of hybridization kinetics does not yield only possible results.
