The Meselson–Stahl experiment, [13] performed by Matthew Meselson and Franklin Stahl in 1958, was the key experiment that provided convincing evidence of semi-conservative replication, the mechanism now known to be correct. Meselson and Stahl described the circumstances leading to this key experiment. [14]
A critical confirmation of the replication mechanism that was implied by the double-helical structure followed in 1958 in the form of the Meselson–Stahl experiment. Messenger RNA (mRNA) was identified as an intermediate between DNA sequences and protein synthesis by Brenner , Meselson , and Jacob in 1961. [ 19 ]

This article presently describes either the experiment or some other background information incompletely. For example, a "dispersive" model of replication where each new double helix consists of a fixed number (say 1000) of base pairs from the original cell, followed by an equal number of new base pairs, and so on would also be consistent with the experimental results.
In probability theory, an event is a subset of outcomes of an experiment (a subset of the sample space) to which a probability is assigned. [1] A single outcome may be an element of many different events, [2] and different events in an experiment are usually not equally likely, since they may include very different groups of outcomes. [3]
Indeed, the definition of an experiment itself has changed in responses to changing norms and practices within particular fields of study. This article documents the history and development of experimental research from its origins in Galileo's study of gravity into the diversely applied method in use today.
An experiment is a procedure carried out to support or refute a hypothesis, or determine the efficacy or likelihood of something previously untried. Experiments provide insight into cause-and-effect by demonstrating what outcome occurs when a particular factor is manipulated.
The history of scientific method considers changes in the methodology of scientific inquiry, not the history of science itself. The development of rules for scientific reasoning has not been straightforward; scientific method has been the subject of intense and recurring debate throughout the history of science, and eminent natural philosophers and scientists have argued for the primacy of ...
