Web13 de set. de 2024 · 1.3 It is relatively easy to extract DNA and protein from cells; biochemists had been doing this since at least the 1800’s. Why then did Hershey and Chase need to use radioactivity to label DNA and proteins in their experiments? 1.4 Compare Watson and Crick’s discovery with Avery, MacLeod and McCarty’s discovery. Web4 de nov. de 2024 · Hershey and Chase labeled the protein coat in one batch of phage using radioactive sulfur, 35 S, because sulfur is found in the amino acids methionine and cysteine but not in nucleic acids. They labeled the DNA in another batch using radioactive phosphorus, 32 P, because phosphorus is found in DNA and RNA but not typically in … kinango is in which county
Hershey & Chase Experiment Experiment, Discovery, & Results
WebHershey and Chase labeled one batch of phage with radioactive sulfur, 35 S, to label the protein coat. Another batch of phage were labeled with radioactive phosphorus, 32 P. Because phosphorous is found in DNA, but not protein, the DNA and not the protein would be tagged with radioactive phosphorus. WebHershey and Chase use radioactivity to label either DNA or proteins. How does this experiment complement the experiment Avery, McCarthy and MacLeod did? A. It doesn't depend on a digestion going to completion B. They got the opposite result to Avery, McCarthy and MacLeod C. They used viruses, while Avery, McCarthy and MacLeod … Web21 de dez. de 2024 · Hershey and Chase concluded that DNA, not protein, was the genetic material.
