Identification of genetic polymorphisms in bovine mitochondrial deoxyribonucleic acid.
In this study, the intent was to identify genetic polymorphisms of mitochondrial (mt) DNA in Korean cattle (Bos taurus coreana) and to analyze the genetic relationship between Korean cattle and other breeds. Whole mtDNA genomes (16,338 bp) of 26 animals (16 Korean cattle and 10 Holsteins) were directly sequenced. Multiple alignments, including 26 whole-mtDNA sequences obtained by direct sequenc...

Triostin antibiotics, which contain a cyclic peptide with a disulphide bridge, have been prepared by growing Streptomyces triostinicus in the presence of inorganic [3PS]sulphate. The labelled triostin A has been shown to behave in all respects similarly to the authentic natural product and to enable a much more sensitive radiochemical adaptation of the solvent-partition method for determining a...

The effects of the three antibiotics U-12,241, nogalamycin, and U-20,661 on (i) deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) synthesis in KB cell cultures and cell-free systems of bacterial and mammalian origin and on (ii) oxidative phosphorylation in rat liver mitochondria were compared. Nogalamycin and U-12,241 inhibited RNA synthesis more strongly than DNA synthesis in all test sys...
متن کاملDeoxyribonucleic acid-deoxyribonucleic acid hybridization assay for replication origin deoxyribonucleic acid of Escherichia coli.
Deoxyribonucleic acid (DNA)-DNA hybridization on nitrocellulose filters can be used to assay for replication origin DNA from Escherichia coli if the DNA attached to the filters is enriched for the replication origin sequences. Such DNA can be readily isolated from very rapidly growing cells. When low amounts of this DNA were attached to filters, radioactively labeled DNA from the replication or...
متن کاملAnalysis of abietic acid and dehydroabietic acid residues in raw ducks and cooked ducks.
Rosin was once widely used for removal of duck feathers in China and is still being used secretly in some poultry processing enterprises. Abietic acid (AA) and dehydroabietic acid (DHAA) are the major compounds of rosin. In the present study, 90 duck samples were collected for investigation of AA and DHAA residues. Abietic acid and DHAA were simultaneously detected in 13 out 40 raw ducks, 8 out...
