What is the molecule that caused transformation in Griffith's mouse experiment?
The molecule that caused transformation in Griffith's mouse experiment was DNA. When heat-killed S strain bacteria (which had DNA) were mixed with live R strain bacteria (which did not), the DNA from the dead S strain bacteria was able to transfer genetic information to the live R strain bacteria, making them pathogenic.
How did Avery and his group determine which molecule was most important for what transformation?
Avery and his group determined which molecule was most important for transformation by selectively destroying different components of heat-killed S strain bacteria and observing which component was necessary to transfer the virulent phenotype to R strain bacteria. They found that the DNA component was responsible for this transformation, leading to the conclusion that DNA was the molecule responsible for genetic information transfer.
The Hershey-Chase experiment disproved which of these molecule groups as the physical carrier of inheritance?
The Hershey-Chase experiment disproved proteins as the physical carrier of inheritance and instead provided evidence that DNA is the primary molecule responsible for transmitting genetic information.
How was Avery and his group determined which molecule was most important for transformation?
Avery and his group created an extract from bacteria that had been killed by heat and then used enzymes to destroy RNA, carbohydrates, lipids, proteins and other such molecules. Because transformation still occurred, they were able to isolate the molecules vital to the process.
Hersheys and chases experiment led to the conclusion that?
Hershey and Chase's experiment using bacteriophages showed that DNA, not protein, is the genetic material responsible for carrying hereditary information. This discovery provided strong evidence for the role of DNA as the molecule of inheritance.
Did Avery and his colleagues think that the molecule required a transformation might also be a molecule of the gene?
Yes, Avery and his colleagues believed that the molecule responsible for the transfer of genetic information in their experiments with pneumonia-causing bacteria (the transforming principle) could be the molecule of the gene. They identified DNA as the molecule responsible for genetic transformation.

What molecule is involved in transformation?
tRNA
Chemical changez is what?
A chemical change is the modification of a molecule, transformation in another type of molecule.
Why does a chemical change differ from a physical change?
A chemical transformation change the structure of the molecule but a physical transformation not.
Avery and his colleagues thought that the molecule required in transformation might also be the molecule of the gene?
This statement refers to Avery's experiment in 1944, where he discovered that DNA is the molecule responsible for carrying genetic information in bacteria. This finding was a crucial step in establishing DNA as the genetic material, leading to further research in molecular biology.
What was Frederick griffin contributions to genetics?
Frederick Griffith, a British bacteriologist, focused on the epidemiology and pathology of bacterial pneumonia. He showed that Streptococcus pneumonia, implicated in many cases of lobar pneumonia,[2] could transform from one strain into a different strain. This was later identified as DNA.
What molecule causes transformation?
Oncogenes are molecules that can cause transformation when mutated or overexpressed. They promote cell growth and division, leading to uncontrolled cell proliferation and eventually tumorigenesis.
Would the formation of ATP molecules from glucose oxidation be an example of energy transformation or conversion?
Yes. It is a good example of energy transformation or conversion. In this energy stored in glucose molecule is released in small pockets. And stored in 38 ATP molecules. Here ADP molecule get converted into ATP molecule. When energy is required, ATP molecule is reconverted into ADP molecule.
What did Avery conclude cause transformation?
Avery concluded that DNA is the molecule that changed bacteria.
What is the first step in a pulse-chase experiment?
Incubating cells with a labeled molecule is the first step in a pulse-chase experiment.
How did Avery and his group determine which molecule was most important for what transformation?
Avery and his group determined which molecule was most important for transformation by selectively destroying different components of heat-killed S strain bacteria and observing which component was necessary to transfer the virulent phenotype to R strain bacteria. They found that the DNA component was responsible for this transformation, leading to the conclusion that DNA was the molecule responsible for genetic information transfer.
