这意味着减数分裂中同源染色体不能配对，染色体间形成的交叉也会更少（例如，在减数分裂早期的重组位点）。
This means that homologous chromosomes failed to pair together during meiosis and chromosomes formed fewer crossovers, i. e. sites where they recombine, during the initial stages of meiosis.
“位点专一重组酶的优势就是酶做了所有的事。”斯达克说，他同时还在调查研究Z FR在遗传工程学中的潜力。
"The advantage of a site-specific recombinase is that the enzyme does everything," says Stark, who is also investigating the potential of ZFRs in genetic engineering.
重组体用克隆位点上游和下游的T7和T3启动子序列为测序引物，用自动测序仪测序鉴定克隆的正确性。
The recombinant was sequenced by automatic sequencer with promoters T7 in upstream and T3 in downstream as sequencing primers.
