A Chemical Is Reported to Inhibit Bacterial Replication

question 26

True/False

A chemical is reported to inhibit bacterial replication. Bacterial cells are placed in medium with all nutrients necessary for replication. The chemical is added to the culture, and after a half hour an extract of the DNA is prepared. A significant percentage of the DNA is in pieces about 1000 to 2000 bases in length. The results are consistent with the chemical blocking the function of DNA ligase.
