Molecular cloning of unintegrated Moloney mouse sarcoma virus DNA in bacteriophage lambda. 1980

I M Verma, and M H Lai, and R A Bosselman, and M A McKennett, and H Fan, and A Berns

The covalently closed circular forms of unintegrated viral DNA obtained from cells infected with Moloney mouse sarcoma virus was cloned in bacteriophage lambda. The viral DNA was cleaved with restriction endonuclease HindIII and inserted in the unique HindIII site of lambda Charon 21A DNA. Recombinant clones containing virus-reactive DNA sequences were analyzed by restriction endonuclease mapping, R-loop formation, and infectivity assays. Two of eight genome-length recombinant clones characterized contained the large terminal repeat. Only the recombinant clones containing the large terminal repeat were able to induce focus formation in uninfected mouse fibroblasts.

D008979 Moloney murine leukemia virus A strain of Murine leukemia virus (LEUKEMIA VIRUS, MURINE) arising during the propagation of S37 mouse sarcoma, and causing lymphoid leukemia in mice. It also infects rats and newborn hamsters. It is apparently transmitted to embryos in utero and to newborns through mother's milk.

D009693 Nucleic Acid Hybridization Widely used technique which exploits the ability of complementary sequences in single-stranded DNAs or RNAs to pair with each other to form a double helix. Hybridization can take place between two complimentary DNA sequences, between a single-stranded DNA and a complementary RNA, or between two RNA sequences. The technique is used to detect and isolate specific sequences, measure homology, or define other characteristics of one or both strands.

D010582 Bacteriophage lambda A temperate inducible phage and type species of the genus lambda-like viruses, in the family SIPHOVIRIDAE. Its natural host is E. coli K12.
