How did beadle and tatum's research result in the one gene-one polypeptide hypothesis?
The major breakthrough in demonstrating the relationship between genes and proteins came in the 1940s. American geneticists George Beadle and Edward Tatum worked with the orange bread mold Neurospora crassa. Beadle and Tatum studied mutant strains of the mold that were unable to grow on the usual nutrient medium. Each of these mutant strains turned out to lack a single enzyme needed to produce some molecule the mold needed, such as a vitamin or an amino acid. Beadle and Tatum also showed that each mutant was defective in a single gene. Their research led them to propose the "one gene-one enzyme" hypothesis. This hypothesis states that the function of an individual gene is to dictate the production of a specific enzyme.Since then, scientists have learned that some genes actually dictate the production of a single polypeptide, which may make up part of an enzyme or another kind of protein. Beadle and Tatum's hypothesis is now generally stated as one gene-one polypeptide.
Why was the one gene one protein hypothesis altered to one gene one polypeptide hypothesis?
Because one gene codes for one polypeptide and some proteins are made of more than one polypeptide and stuck together after translation of the genes that code for these polypeptides. Not sure if there ever was a one gene one protein hypothesis or if its just something they teach in schools to avoid overcomplicating things.
Compare and contrast a theory with a hypothesis?
A theory is a well-substantiated explanation of some aspect of the natural world that is based on a body of facts that have been repeatedly confirmed through observation and experimentation. A hypothesis, on the other hand, is a specific, testable prediction about what will happen in a given set of circumstances. In simple terms, a theory explains why something happens, while a hypothesis predicts what will happen.
What is the substrate for phenolase?
The substrate for the enzyme phenolase is phenol.
Every hypothesis must be tested Do you agree or disagree Explain your answer and give an example of a hypothesis?
I don't agree that every hypothesis MUST be tested. In order to advance to the status of a scientific theory, a hypothesis must be tested. Otherwise it remains a mere hypothesis. But some hypotheses are beyond our present capacity to test. Hypothesis: there are technologically advanced alien civilizations in our galaxy on planets other than the Earth. Method of testing: explore the galaxy in space ships. Except that we don't really have any interstellar space ships (it's hard enough just getting to the moon!) and the process of exploring the galaxy would be so expensive and so time-consuming that we really could not afford it in our present economic state.

What must scientist do if the hypothesis is not supported by experimental results?
You can perform the experiment again to check for errors. The best option is to just state in the conclusion the sources of error and why the experiment didn't support the hypothesis. Remember the hypothesis is only an educated guess.
What is a bad hypothesis or a wrong hypothesis?
there is never really a wrong hypothesis because its basically just a guess....
Why hypothesis always explicit?
no hypothesis is explicit because it is just a guess ~.~
Make a sentence about Hypothesis?
You just did it, If you don't do your hypothesis you will be missing a step on the project.
How do you state that your hypothesis was correct?
Ho- the profitability ratio of idbi is greater than those of kotak bank H1 - the profitability ratio of kotak bank is greater than those of idbi bank
What enzymes are in our body?
Just about every reaction in our bodies is regulated by an enzyme. The word enzyme is just another word for catalyst.
What helps an enzyme to bind to a specific active site?
What? Enzyme doent look for another enzmes active site! it just look for its substrate to bind at in its active site! This will in turn make it to form any by products or convert it from the actual state!
What was Pasteurs hypothesis?
pasteures hypothesis was if microorganisms could just spontaneously appear out of nonliving thing
What is a hypothesis and how do you form one?
a hypothesis is like a descriptive ideayou don't FORM one. it is just made for you to use, so USE IT. A HYPOTHESIS is a guess about some thing important or just about anything i guess.
Why is a hypothesis not just a guess?
Unlike a wild guess, a hypothesis is based on observations and it must be testable......:-) answer by hismejohn
