[Cloning of the DNA BglII fragments of bacteriophage T4 in the vector plasmid pSCC31].
An attempt has been made to clone six BglII fragments of T4 DNA in the range of 3.3-8.1 kb in the vector plasmid pSCC31 containing a single BglII site within the gene for endonuclease EcoRI and pL promoter of phage lambda. DNA fragments were extracted from the corresponding bands of agarose gel. The following BglII fragments were cloned: the 3.3 kb fragment No. 9 containing a portion of gene 20, the gene 21 and a portion of gene 22; the 4.2 kb fragment No. 8.1 with genes 17, 18, 19 and a portion of gene 20; the 5.2 kb fragment No. 7.1 with genes 25-29 and a portion of gene 48. In the case of the fragment No. 7.1, the recombinant plasmids pRL705 and pRL707 with different orientation of phage DNA fragment were obtained. An attempt to clone the fragments No. 8.2 (4.2 kb), No. 7.2 (5.45 kb) and No. 6 (8.1 kb) was unsuccessful and this probably indicates the presence of the genes, whose products are deleterious to the growth of bacterial cell.
