What Would Hershey And Chase Have Concluded If Both Radioactive 32P And 35S?

What would Hershey and Chase have concluded if both radioactive 32p and 35s were found in the bacteria after their experiment? –

Both virus's protein coat and its DNA were injected into the bacteria

. Both virus's protein coat and its DNA were injected into the bacteria. You just studied 20 terms!

What would Hershey and Chase have concluded if both radioactive P and S were found in the bacteria in their experiment?

The mice were unaffected. What would Hershey and Chase have concluded if both radioactive

³²

P and

³⁵

S were found in the bacteria in their experiment?

The virus's protein coat was not injected into the bacteria.

… Both the virus's protein coat and its DNA were injected into the bacteria.

Why did Hershey and Chase use 32P and 35S in their experiments instead of the radioactive isotopes 14c or 13n quizlet?

Why were 32P and 35S chosen for use in the Hershey/Chase experiment? …

The experiment demonstrated that most of the 32p-labeled material (DNA) was injected, which the phage ghosts (protein coats) remained outside of the bacterium

. Therefore, nucleic acid/DNA must be the genetic material.

What would Hershey and Chase have concluded if they had found radioactive sulfur instead of phosphorus in infected bacteria cells?

If Hershey and Chase had found radioactive sulfur instead of phosphorus in infected bacteria cells they would have concluded that

the protein coat of the bacteriophage was involved in the transformation of the E. coli

.

Why did Hershey and Chase use the isotopes 32P and 35S in their experiments?

What technique did Hershey and Chase use to study the viruses in their experiments? They used radioactive isotopes of phosphorus-32 and

sulfur-35 as markers so they could trace the proteins and DNA to see what they were doing to the cell

.

What did the Hershey-Chase experiment prove?

The Hershey-Chase experiment, which demonstrated that

the genetic material of phage is DNA, not protein

. The experiment uses two sets of T2 bacteriophages. In one set, the protein coat is labeled with radioactive sulfur (

³⁵

S), not found in DNA. … DNA was thought to be a rather simple chemical.

What is the conclusion of Hershey and Chase's experiments?

Hershey and Chase concluded

that protein was not genetic material, and that DNA was genetic material

. Unlike Avery's experiments on bacterial transformations, the Hershey-Chase experiments were more widely and immediately accepted among scientists.

How did Hershey and Chase use radioactivity to draw a conclusion?

Hershey and Chase studied

bacteriophages

which are viruses that attack bacteria. They labeled the bacteriophage with radioactive isotopes to see where it goes when a virus attacks. They discovered that nearly all the radioactivity was found in phosphorus, confirming that DNA contains genetic material, not protein.

Why was s35 used in this experiment?

Why were phosphorus-32 and sulfur-35 perfect for what Hershey & Chase were investigating in their experiments? They were perfect

because proteins contain almost no phosphorus and DNA contains no sulfur

, so the radioactive isotopes would show up in the cells if the phosphorus-32 or sulfur-35 appeared.

What are the 3 key roles of DNA?

DNA now has three distinct functions—

genetics, immunological, and structural

—that are widely disparate and variously dependent on the sugar phosphate backbone and the bases.

What is are the conclusion of Blender's experiment?

1952: Geneticists Alfred Hershey and Martha Chase publish the findings of their so-called blender experiments, which conclude that

DNA is where life's hereditary data is found

. … Using the blender, Hershey and Chase separated the protein coating from the nuclei of bacteriophages, the viruses that infect bacteria.

What happens when a piece of DNA is missing?

What happens when a piece of DNA is missing?

Genetic information is lost

. … Genetic information is copied.

Why were bacteriophages used in the Hershey Chase experiment?

Importantly, they showed that

phage DNA enters the host cell and directs phage reproduction

. This showed that DNA was the genetic material that was passed down from the virus to a cell and thus DNA was the material that is passed from a cell to another cell.

Is sulfur a DNA?

They also knew that proteins contain

sulfur

atoms but no phosphorus, while DNA contains a great deal of phosphorus and no sulfur.

Why did Hershey and Chase not tag the nitrogen component of DNA?

For a science fair project, two students decided to repeat the Hershey and Chase experiment, with modifications. They decided to label the nitrogen of the DNA, rather than the phosphate. … Thus, labeling the nitrogens

would provide a stronger signal than labeling

the phosphates.

What were the main criteria taken under consideration for the experiment by Hershey and Chase?

What were the main criteria taken under consideration for the experiment by Hershey and Chase? … Explanation: The two factors considered by Hershey and Chase were

the simple composition of T2 bacteriophage, that is, DNA and protein

. Thus radiolabelling of only one element was required.
