Question

In 1958, Meselson and Stahl conducted an experiment to determine which of the three proposed methods of DNA replication was correct. Identify the three proposed models for DNA replication. Conservative Semiconservative Dispersive . Answer Bank The Meselson and Stahl experiment starts with E. coli containing 1sN/SN labeled DNA grown in 14N media. Which result did Meselson and Stahl observe by sedimentation equilibrium centrifugation to provide strong evidence for the semiconservative model of DNA replication? O The first generation has hybrid ^15N/^14N DNA and the second generation has both hybrid ^15N/^14N and ^14N/^14N DNA. No ^15N/^15N DNA was observed. O Both the first and second generation have both ^15N/^15N DNA and ^14N/^14N DNA. No hybrid ^15N/^14N DNA was observed. O The first generation has hybrid ^15N/^14N and the second generation has hybrid ^15N/^14N DNA. No ^15N/^15N DNA nor ^14N/^14N DNA was observed.

Answer 1

Step-by-step explanation:

because goody addams was sacraficed for this experiment so when the experiment was done Wednesday addams was born
