Molecular cloning of extensive sequences of the in vitro synthesized chicken ovalbumin structural gene

Double-stranded DNA molecules complementary to ovalbumin chicken messenger RNA were synthesized in vitro and integrated into the E. coli plasmid pCR1 using an oligodG-dc tailing procedure. The resultant hybrid plasmids, amplified by transfection of E. coli, were shown by hybridization and gel electrophoresis to contain extensive DNA sequences of the ovalbumin structural gene.
