Abstract
Ultra-violet irradiation of lambda phage results in an inhibition of conversion of lambda DNA in host cells from the initial linear form to twisted circular form. The formation of open circular lambda DNA in vitro (formation of Hershey's circle) was quite resistant to the irradiation. The occurrence of denaturation of ultraviolet irradiation was detected in lambda DNA.
摘要
λ噬菌体的紫外线照射会抑制宿主细胞中λDNA从最初的线性形式转化为扭曲的环状形式。体外开放环状λDNA的形成（赫尔希环的形成）对辐射相当耐受。在λDNA中检测到紫外线照射引起的变性现象。
