A temperature sensitive nonsense mutation affecting the synthesis of a major protein of Escherichia coli K12.
A temperature sensitive nonsense (TSN) mutant of E. coli K12 has been isolated in which a major bacterial protein is not synthesized at 42 degrees C. This protein is found in the parental strain at 42 degrees C and in cells rendered temperature resistant due to the insertion of a number of different nonsense suppressors or the normal allele of the mutant locus.

Replication of deoxyribonucleic acid during the division cycle of Salmonella typhimurium.
The rate of thymidine incorporation into cells of Salmonella typhimurium growing in different media has been measured. In glucose-minimal medium, deoxyribonucleic acid (DNA) replication occurs during the first two-thirds of the division cycle; the final one-third of the division cycle was devoid of DNA replication. The measured doubling time of S. typhimurium in this medium is approximately 48 min, indicating that C (the time for a round of replication) and D (the time between termination and cell division) are approximately 32 and 16 min, respectively. At slower growth rates the pattern of replication is the same as glucose minimal medium. At faster growth rates the "gap" in DNA synthesis disappears. At rapid growth rates evidence for multiple forks is obtained.
