[Simian adenovirus type 7 (SA7) DNA fragmentation by specific R.Bgl II and R.Hind III endonucleases]

The effect of restricting R. BgIII and R. HindIII endonucleases on the genome of simian adenovirus type 7 (SA7) was studied. The R. BgIII endonuclease has 5 restriction sites on SA7 DNA and produces 6 fragments with molecular weights of 10.0 X 10(6), 5,3 X 10(6), 3.6 X 10(6), 1.8 X 10(6), 0.6 X 10(6), and 0.5 X 10(6) daltons. R. HindIII, having 3 restriction sites, hydrolyses SA7 DNA into 4 fragments with molecular weights of 7.6 X 10(6), 5.9 X 10(6), 5,2 X 10(6), 3,1 X 10(6) daltons. The R. BgIII and R. HindIII fragments are arranged in the SA7 genome in the following order: B-A-C-E-D-F and C-D-B-A.
