Hershey and chase used to radioactively label
WitrynaExpert Answer. 23. For a science fair project, two students decided to repeat the Hershey and Chase experiment, with modifications. They decided to label nitrogen of the DNA, rather than the phosphate. They reasoned that each nucleotide has only one phosphate and two to five nitrogens. Thus, labeling nitrogens would provide a … WitrynaView the full answer. Transcribed image text: 2. For a science fair project, two students decided to repeat the Hershey and Chase experiment, with modifications. They decided to radioactively label the nitrogen of the DNA, rather than the phosphate. They reasoned that each nucleotide has only one phosphate and two to five nitrogen atoms.

WitrynaExperimental Design: In order to decipher what the genetic material is, Hershey and Chase needed to isolate the two variables; protein and DNA. They used a certain type of virus called the T-2 bacteriophage in their experiment, a virus made up of DNA and a protein shell, pictured below. The phage works by attaching itself to its host bacterium ... WitrynaHershey and Chase radioactively labeled T2 bacteriaphages; the protein component with radioactive sulfur and the DNA component with radioactive phosphorous. Then, they let the T2 phages react with E. coli bacteria, using a warring blender to shear off the protein heads of the phages and centrifuging the resultant mixture of bacteria with ...
WitrynaExplain why Hershey and Chase used radioactive sulfur to label the protein coat while using radioactive phosphorus to label the DNA. They used radioactive sulfur to label … 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 intact. 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 the phage subsections.
