Is that between pREB7 and pREB8, with 29 of pREB7 (or 38 of pREB8) nucleotides sharing 75 identity. The matching regions range from 100 to 8,500 bp with an average of 1,800 bp. Several plasmids also share a few very large homologous regions ( 10 kbp) but do not share a significant global sequence identity. The internal homology between all A. marina plasmids exceeds that seen between its plasmi
