Transposition of Tn1000: activity of single or directly repeated termini.

AUTOR(ES)
RESUMO

Tn1000 (gamma delta) termini IRR and IRL, or direct repetitions of IRR-IRL carried by pBR322 derivatives mediate cointegration with pOX38 at similar rates. Structures of product plasmids indicate that the transposed segments correspond to DNA bounded by IR segments in the donor plasmid. Such structures could arise by symmetric transposition from a replication intermediate.
