Abstract
Newly synthesized DNA is undermethylated in E. coli K-12. The amount of N6-methyl deoxyadenylic acid in labeled DNA varied from 0.3 mol% of total adenine for a 2-min pulse to 1.7 mol% for DNA that was labeled for more than two generations.
摘要
新合成的DNA在大肠杆菌K-12中处于低甲基化状态。标记DNA中N6-甲基脱氧腺苷酸的含量，对于2分钟脉冲标记的DNA，占腺嘌呤总量的0.3摩尔%；对于标记超过两代的DNA，则为1.7摩尔%。
