متن کاملIsolation of deoxyribonucleic acid from mammalian tissues.
1. DNA has been isolated from different mammalian tissues. The DNA preparations were free from RNA, protein and polysaccharides and have a similar range of sedimentation coefficients (approx. 24s). 2. Protein was removed by a two-stage extraction with a phenol-cresol mixture by using a detergent with 4-aminosalicylate in the first stage and sodium chloride in the second. 3. Polysaccharides rema...
متن کاملInduced Polynucleotide Kinase, Polynucleotide Ligase, and Deoxyribonucleic Acid Polymeraset
The mechanism of action of T4-induced polynu-cleotide kinase on short single-stranded deoxyoligonucleotideshas been investigated.It was found that the phosphorylationreaction catalyzed by T, polynucleotide kinase could be re-versed. Thus, a 5 ’-3*P-labeleddeoxyoligonucleotide and ADPon incubation with the enzyme formed [Y-~~PJATP.In addi-tion some radioac...
متن کاملRole for deoxyribonucleic acid ligase in deoxyribonucleic acid polymerase i-dependent repair synthesis in toluene-treated escherichia coli.
In a toluene-treated mutant of Escherichia coli K-12 having a temperature-sensitive, conditionally lethal mutation in the structural gene for deoxyribonucleic acid (DNA) ligase, an extensive DNA repair synthesis occurred in X-irradiated cells at the nonpermissive temperature, 42 C. At the permissive temperature, 30 C, nearly normal semiconservative synthesis and limited repair synthesis were ob...
متن کاملEffect of drugs on deoxyribonucleic acid synthesis in isolated mammalian cell nuclei. Comparison with partially purified deoxyribonucleic acid polymerases.
In order to ascertain the identity of the DNA-dependent DNA polymerase responsible for the observed DNA synthesis in nuclei isolated from baby-hamster kidney (BHK-21/C13) cells a comparative study was carried out on the effects of some drugs, reported to influence DNA synthesis, on DNA synthesis catalysed by these nuclei and by partially purified DNA polymerase-alpha and -beta. In all cases DNA...
