Web3 jan. 2024 · Stahl himself notes that the results exhibit notable clarity in the sense that there is no need for their interpretation, they exhibit a sense of completeness and conclusiveness. Footnote 5 Fischer further adds that “the Meselson-Stahl experiments speak for themselves and made all further commentary superfluous” (1999, 21). The Meselson–Stahl experiment is an experiment by Matthew Meselson and Franklin Stahl in 1958 which supported Watson and Crick's hypothesis that DNA replication was semiconservative. In semiconservative replication, when the double-stranded DNA helix is replicated, each of the two new double-stranded DNA helices consisted of one strand from the original helix and one newly synthesized. It has been called "the most beautiful experiment in biology." Meselson and Stahl …
WebMeselson and Stahl investigated DNA replication by first feeding bacteria with bases containing 15N (heavy), and then with bases containing 14N (light). The results are shown in the photographs. From this information, what would be the composition of the DNA in generation 3? answer choices There will be a single 14N band.
Web6 sep. 2024 · Meselson and Stahl could tell from this result that the DNA was being copied in a semi-conservative way. The pattern of two distinct bands—one where a hybrid molecule should be and one where a light molecule should be—is exactly what we’d expect from semi-conservative replication (as illustrated in the diagram below).
