We have combined techniques of genetic and physical mapping with rapid DNA sequence analysis to identify the nucleotide change in lambda int mutations. These mutations define two dominant phenotypic classes: (i) recombination that is partially independent of accessory factors, and (ii) inhibition of wild-type Int by missense or nonsense proteins, i.e., negative complementation.
我们将遗传图谱和物理图谱技术与快速DNA序列分析相结合,以鉴定λ整合酶(Int)突变中的核苷酸变化。这些突变定义了两个主要的表型类别:(i)部分独立于辅助因子的重组,以及(ii)错义或无义蛋白对野生型Int的抑制作用,即负互补。
