到1987年,T。
到目前為止,運用基因同源重組、非同源末端 連接(non- homologous end-joining, NHEJ)或 同源 指導修復(homology-directed repair, HDR )進 行基因敲除(替換)依然是構建基因敲除 (遺傳 修飾)動物模型中最普遍的使用方法。

3. Homologous recombination
❖Cre/loxP System or Cre-Lox recombination
Cre (Causes Recombination) ; loxP (locus of crossing (x) over, P1)
- results in: - endogenous DNA replaced with exogenous - specific - targeted - copy number = 1
