RESUMO
Complementary DNA (cDNA) was transcribed from a polyadenylated sea urchin histone mRNA preparation isolated by density gradient centrifugation. By hybridization, this cDNA was shown to be extensively contaminated (85% of hybridizable cDNA) with DNA complementary to RNA derived from the large ribosomal subunit. Purification of a mRNA specific cDNA fraction was achieved by hybridization of purified rRNA to cDNA followed by fractionation on hydroxyapatite. After further purification to remove nonhybridizable cDNA our purified cDNA showed only 8% hybirdization to rRNA.
