1 And in the downstream region of the replicase gene , it existed multi - tandem repeat of 17 bps.

2 Given the properties of reverse transcriptase and RNA replicase, can you suggest a reason for the small size of these viral genomes?

3 This particular formula is well adapted to an environment consisting of test-tubes provided with ready-made replicase.

4 Further characterization of the DEN replication complex (RC) showed the involvement of NS1, NS2A, NS3, NS4A, and NS5 proteins as the viral replicase.

5 It was a kind of promising method to use viral replicase gene in anti-virus plant genetic engineering.
