Studies involving lambda phage transduction of the D-arabinose utilization gene (dar+) in Escherichia coli K-12 indicated the product of this gene to be a transdominant activator. An apparent anomaly regarding this hypothesis exists in that a diploid recessive lysogen (lambda dar-/dar-) can spontaneously become capable of growth on D-arabinose.
涉及大肠杆菌K-12中D-阿拉伯糖利用基因(dar+)的λ噬菌体转导研究表明,该基因的产物是一种反式显性激活因子。关于这一假设存在一个明显的异常情况,即二倍体隐性溶原菌(λdar-/dar-)能够自发地在D-阿拉伯糖上生长。
