Witryna5 mar 2024 · In the 1950s, Alfred Hershey and Martha Chase did experiments with virusesand bacteria. Virusesare not made of cells. They are basically DNA inside a protein coat. To reproduce, a virus must insert its own genetic material into a cell (such as a bacterium). Then it uses the cell’s machinery to make more viruses. Hershey and Chase showed that the introduction of deoxyribonuclease (referred to as DNase), an enzyme that breaks down DNA, into a solution containing the labeled bacteriophages did not introduce any 32 P into the solution. This demonstrated that the phage is resistant to the enzyme while … Zobacz więcej The Hershey–Chase experiments were a series of experiments conducted in 1952 by Alfred Hershey and Martha Chase that helped to confirm that DNA is genetic material. While DNA … Zobacz więcej Hershey and Chase needed to be able to examine different parts of the phages they were studying separately, so they needed to distinguish … Zobacz więcej The Hershey–Chase experiment, its predecessors, such as the Avery–MacLeod–McCarty experiment, and successors served to unequivocally establish that … Zobacz więcej In the early twentieth century, biologists thought that proteins carried genetic information.
