Abstract

Specific fragmentation of T7 DNA at glyoxal-fixed denatured regions by the S1 endonuclease followed by restriction analysis made it possible to localize four low-melting regions in phage T7 DNA. These regions have the following coordinates:0.5-1.2;14.8±0.3;46.3±0.5; 98.4±0.3 (in T7 DNA length units). The location of the low-melting regions was refined by means of electron-microscopic denaturation mapping and gel electrophoresis of partially denatured DNA. The obtained localization of the low-melting regions is consistent with the available data on the sequence of T7 DNA. The map of low-melting regions was compared with the genetic map of T7 DNA.
