Question
Chapter 14, Problem 2DA
Summary Introduction
To determine: The products of a third round of replication in Meselson and Stahl’s experiment.
Introduction: Meselson and Stahl were the first to propose the semi-conservative mode of replication of DNA. They proved this replication feature by observing the pattern of replication in E. coli cells.

What is meant by the semiconservative nature of DNA replication?
Suppose that replication is initiated in a medium containing moderately radioactive tritiated thymine. After a few minutes of incubation, the bacteria are transferred to a medium containing highly radioactive tritiated thymidine. Sketch the autoradiographic pattern that would be seen for (a) undirectional replication and (b) bidirectional replication, each from a single origin.
Where does is the origin of replication?
