[Selection and some properties of recombinant clones of lambda bacteriophage containing structural genes of Drosophila melanogaster].
The lambdagt clones containing fragments of D. melanogaster genome were prepared and characterized by hybridization of their DNA with complementary RNA synthesized on the lambdagt DNA, C fragment of lambdagt DNA and total D. melanogaster DNA, and also with mRNA and a stable cytoplasmic poly(A)-RNA both isolated from D. melanogaster cells grown in culture. The technique for a simple selection of hybrid clones is described. The hybridization with mRNA allows one to select the clones containing structural genes of D. melanogaster. It was found that in all cases when the clone contains the structural gene it also contains the reiterated base sequences of the D. melanogaster genome. Several clones containing D. melanogaster DNA fragments with a size of (2--4) X 10(6) daltons which hybridized with a relatively large portion of mRNA were selcted for further analysis.
