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!
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 results would you expect if the bacteriophage that Hershey and Chase used in their experiment had contained RNA instead of DNA?
What results would you expect if the bacteriophage that Hershey and Chase used in their experiment had contained RNA instead of DNA? The results would be the same. coli bacteria that were infected with T2 bacteriophage that have been labeled with either 32P or 35S.
What was the significance of the radioactive isotopes Hershey and Chase chose?
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 was the result of Hershey and Chase’s experiment?
Hershey and Chase concluded that DNA, not protein, was the genetic material. They determined that a protective protein coat was formed around the bacteriophage, but that the internal DNA is what conferred its ability to produce progeny inside a bacterium.
What was the result of Hershey and Chase’s experiment with viral infection of bacteria?
The blender maintains any phage material that entered the bacterial cell. The sample that they did not stir had more of the sulfur-labeled protein because the protein coats remained on the outside of the cell. Hershey and Chase concluded that protein was not genetic material, and that DNA was genetic material.
What is are the conclusion of Blender’s experiment?
After Alfred Hershey and Martha Chase, DNA steps up to the plate. 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.
Why did Hershey and Chase use bacteriophages?
Bacteriophages were used because they contain little more than DNA and protein. Alfred Hershey and Martha Chase used the bacteriophages because of their connection to DNA. In one batch, the phages (short for bacteriophages) were grown with radioactive phosphorous, which means it was incorporated into phage DNA.
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.
Which of the following is not a type of reverse mutation?
Which of the following is NOT a type of reverse mutation? Explanation: Reverse mutation occurs at the same or different sites of forward mutation and restores wild phenotype. 5.
How is the genetic material expressed?
Gene expression is the process by which the information encoded in a gene is used to direct the assembly of a protein molecule. The cell reads the sequence of the gene in groups of three bases. Each group of three bases (codon) corresponds to one of 20 different amino acids used to build the protein.
Which of the following is wrongly paired?
2. Which of the following is wrongly paired? Explanation: Nucleic acids, that is, DNA and RNA show phosphodiesterase linkage which is the major type of linkage. Without the phosphodiester bonds between the phosphate and adjacent 3’OH sugar molecule the backbone will not be formed.
Which respect to nucleosides Which of the following is paired correctly?
Q3: With respect to nucleosides, which of the following is correctly paired? Explanation: Purines (adenosine and guanine) have a fused ring structure with 9-element backbones ring structure . Cytidine, thymidine and uridine are pyrimidines with a ring structure of 6 carbons in the backbone.
Which Indian state is wrongly paired?
Sabarigiri Hydroelectric Project Kerala is located in the Moozhiyar of Pathanamthitta district in the state of Kerala in India. The power project is commissioned in 1966 with an installed capacity of 300 MW.
What are the three components needed for protein synthesis?
It includes three steps: initiation, elongation, and termination. After the mRNA is processed, it carries the instructions to a ribosome in the cytoplasm. Translation occurs at the ribosome, which consists of rRNA and proteins.
How does protein synthesis work?
The molecule of mRNA provides the code to synthesize a protein. In the process of translation, the mRNA attaches to a ribosome. Next, tRNA molecules shuttle the appropriate amino acids to the ribosome, one-by-one, coded by sequential triplet codons on the mRNA, until the protein is fully synthesized.
What is the function of ribosome in protein synthesis?
The ribosome is universally responsible for synthesizing proteins by translating the genetic code transcribed in mRNA into an amino acid sequence. Ribosomes use cellular accessory proteins, soluble transfer RNAs, and metabolic energy to accomplish the initiation, elongation, and termination of peptide synthesis.
Where the first step of protein synthesis occur?
nucleus
