Which of the following facts did Hershey and Chase make use of in trying to determine whether DNA or protein is the genetic material quizlet?
In trying to determine whether DNA or protein is the genetic material, Hershey and Chase made use of which of the following facts? Answer: DNA contains phosphorus, whereas protein does not.
What was the Hershey Chase experiment designed to determine?
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.
Which characteristics allowed Hershey and Chase to determine whether the genetic material was made of DNA protein?
Which of the following characteristics allowed Hershey and Chase to determine whether the genetic material was made of DNA or protein? DNA contains phosphorus, whereas protein does not. Like Hershey and Chase they used radioactive sulfur but they substituted radioactive nitrogen for radioactive phosphate.
Which characteristics allowed Hershey and Chase to determine?
What was the key factor that allowed Hershey and Chase to show that DNA alone carried the genetic information of a bacteriophage? DNA contains phosphorus, but protein does not. Protein contains sulfur, but DNA does not. This allowed radioactive phosphorus and radioactive sulfur to identity each molecule specifically.
What are the 3 key roles of DNA?
What are the three key roles of DNA? Storing, copying, and transmitting information.
What conclusion can be drawn from the bacteria experiment?
He concluded that heat-killed S strain bacteria passed on their genetic material to the offspring, so the harmless bacteria transformed into the type that causes pneumonia. He named the process transformation and concluded that gene was a transforming factor.
Which was a conclusion of Griffith’s work with Streptococcus?
Griffith concluded that the type II-R had been “transformed” into the lethal III-S strain by a “transforming principle” that was somehow part of the dead III-S strain bacteria.
What did Avery’s experiment prove?
In a very simple experiment, Oswald Avery’s group showed that DNA was the “transforming principle.” When isolated from one strain of bacteria, DNA was able to transform another strain and confer characteristics onto that second strain.
What was the main outcome of Griffith’s experiments?
Griffith concluded that the heat-killed bacteria somehow converted live avirulent cells to virulent cells, and he called the component of the dead S-type bacteria the “transforming principle.” Fig. 1.1. Schematic diagram of Griffith’s experiment which demonstrates bacterial transformation.
What did Avery conclude?
What did Avery conclude? He concluded that DNA transmits genetic information.
What did Hershey and Chase conclude?
Hershey and Chase concluded that protein was not genetic material, and that DNA was genetic material. The Hershey-Chase experiments mostly ended scientists’ suspicions that genes were made of protein rather than DNA.
Which bacteria killed the Mason Griffiths transformation experiment?
If protein had been responsible for carrying genetic information, Hershey and Chase would have observed that their bacteria were marked with radioactive sulfur. In Griffith’s experiment, he mixed heat-killed S-strain bacteria with live, harmless bacteria from the R-strain.
What property of DNA does bacterial transformation illustrate group of answer choices?
What property of DNA does bacterial transformation illustrate? Bacterial DNA cannot move into other bacteria and function. Bacterial DNA can move into another bacteria and function. Bacterial DNA uses four nucleotides bases that work in pairs.
What happens when a piece of DNA is missing group of answer choices?
What happens when a piece of DNA is missing? Genetic information is lost. Genetic information is transmitted.
What property of DNA does bacterial transformation illustrate quizlet?
What property of DNA does bacterial transformation illustrate? Bacterial DNA can move into another bacteria and function. there is a chemical that contains genetic information that can be passed from one organism to another.
What are three tasks that DNA must be able to perform in all organisms select three answer choices?
What are three tasks that DNA must be able to perform in all organisms? It must store genetic information, instruct cells to produce needed molecules, & copy itself.
What is needed for DNA replication select all that apply?
Answer: The things needed for DNA replication are: For two identical DNA molecules to be produced, the parent DNA molecule will be unwound by an enzyme known as helicase which breaks the hydrogen bonds between the nitrogenous bases of the two DNA strands thereby separating the two strands.
What did the experiment of Griffith and Avery show about genetic information?
what type of experiments of Griffith and Avery show about genetic information? Griffith and Avery studied bacteria and mice. Their S and R experiment revealed that DNA stores and transmits genetic information from one generation of bacteria to another. Chromosomes consist of protein and DNA, but mainly DNA.
Why did Hershey and Chase use s35 and p32?
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 did Avery Griffith and Hershey and Chase’s experiments determine?
Groundbreaking experiments by Griffith, Avery, Hershey, and Chase disproved the notion that proteins were genetic material. Together, these experiments demonstrated that DNA was transferred between generations and that this molecule had the ability to transform the properties of a cell.
