A Synthetic, Partial Pre-mRNA for Ovalbumin Primes Its Own Complementary DNA with Reverse Transcriptase

Synthetic, partial pre-mRNA for ovalbumin was found to prime its own cDNA with reverse transcriptase. Initiation of the cDNA occurred 36 bases upstream of the 3'-end of the RNA, probably as a result of intramolecular base pairing at this end. Inhibition of self-priming occurs following ligation of pCp or poly-adenylation at the 3'-terminus of the synthetic RNA. The secondary structure of 3'-end region of the template RNA strongly affected the ability of self-priming.
