Detailed explanation-1: -Meselson and Stahl Experiment was an experimental proof for semiconservative DNA replication. In 1958, Matthew Meselson and Franklin Stahl conducted an experiment on E.coli which divides in 20 minutes, to study the replication of DNA.
Detailed explanation-2: -The experiment done by Meselson and Stahl demonstrated that DNA replicated semi-conservatively, meaning that each strand in a DNA molecule serves as a template for synthesis of a new, complementary strand.
Detailed explanation-3: -Meselson and Stahl Experiment: Introduction The semiconservative replication of DNA was proposed by Watson and Crick. This model states that the DNA’s two strands split apart and for the synthesis of a new strand, each strand serves as a template.
Detailed explanation-4: -Meselson & Stahl reasoned that these experiments showed that DNA replication was semi-conservative: the DNA strands separate and each makes a copy of itself, so that each daughter molecule comprises one “old” and one “new” strand.
