β¦ Synopsis
A physical map of the group A streptococcal bacteriophage A25 genome was constructed using data obtained from restriction enzyme digestion analysis of purified DNA. Phage A25 was 34.6 kb in size and was digested with several enzymes which generated the following number of fragments: AvuI (3), EcoRI (2), Hind11 (4), Hue11 (lo), Hind1 ( 22), HpaI (Il), and PvuII (8). Restriction enzymes BamH1, PstI, and Sun did not cleave phage A25 DNA. A physical map of the group C streptococcal phage C1 genome was also constructed. Phage C1 was 16.9 kb in size and was cleaved by the following enzymes to give the indicated number of fragments; EcoRI (8), Hue11 (4), Hue111 (lo), HindIII (5), HpaI (8), PvuII (3), and Sun (2). Restriction enzymes AvuI, AvuII, BumH1, EcoRV, HpaII, and PsrI did not cleave phage C1 DNA.

A restriction map has been constructed for the DNA of coliphage T1 which locates the cleavage sites of the restriction endonucleases, BglI (6 cuts), BglII (16 cuts), EcoRI (2 cuts), HindIII (2 cuts) and PstI (2 cuts). Digestions with BglI and BglII reveal fragments which are present in sub-molar qua
Comparative restriction cleavage analysis of the genomes of bacteriophage P7, of several recombinant phages between P7 and P1, and of bacteriophage P1 allowed to draw PstI, Bg/II, BamHI and HindIII cleavage maps of all genomes studied. The data obtained complement Yun and Vapnek's (1977) conclusions
Overlapping restriction fragments of chloroplast DNA from the conifer Pinus contorta were cloned. Out of a total of 49 clones, 33 comprise the minimum set required to represent the entire genome. Using the purified inserts of these clones as probes in filter hybridizations, all sites for the three r
We present a linearized physical map of the genome of bacteriophage T4. This map contains the cleavage sites for restriction enzymes SmaI, KpnI, SalI, BglII, XhoI, XbaI, ClaI , HaeII, EcoRI, and EcoRV . It also contains about 200 TaqI sites. The promoter sites recognized in vitro and a number of rho
Natural recombinant genomes between several, phenotypically distinct forms of phages kappa and theta were isolated and characterized by DNA restriction fragment mapping and electron microscopic heteroduplex analysis. The phenotypes of the recombinants were correlated with the physical maps of the ge
