Loss of deoxyribonucleic acid-thymine during thymine starvation of Escherichia coli.
نویسندگان
چکیده
A substantial loss of deoxyribonucleic acid-thymine occurs during thymine starvation of several thymine auxotrophs derived from Escherichia coli strains B, 15, and K-12.

متن کاملInfluence of thymine starvation on the integrity of deoxyribonucleic acid in Escherichia coli.
The influence of thymine starvation on the single-strand molecular weight of deoxyribonucleic acid (DNA) from Escherichia coli was determined by sedimentation through gradients of alkaline sucrose. Growth of cells for as long as 150 min in thymineless medium did not significantly reduce the molecular weight below the control value of 2.4 +/- 0.3 x 10(8) daltons. Incubation of cells in thyminele...
