In cystic fibrosis a change in a single gene caused the protein called CFTR to?
fold improperly
What change causes the protein CFTR fold improperly?
A mutation in the CFTR gene causes the protein CFTR to fold improperly. This mutation results in a defective CFTR protein that cannot function properly, leading to the development of cystic fibrosis.
How can one test for protein in a sample?
One can test for protein in a sample by using a method called the Biuret test. This test involves adding a reagent to the sample, which causes a color change if protein is present. The intensity of the color change can indicate the amount of protein in the sample.
What is a change in the normal confirmation of a protein that often results in loss of protein function called?
A change in the normal confirmation of a protein that results in loss of protein function is called denaturation. This can be caused by factors such as heat, pH changes, or exposure to chemicals. Denaturation disrupts the protein's structure, leading to loss of its normal biological activity.
What is it called when there is a change in the three-dimensional shape of a protein?
It is called "Denaturing" of proteins.
Process causing protein shape to change in response to heat?
The process that causes protein shape to change in response to heat is called denaturation. When proteins are exposed to high temperatures, the interactions that maintain their specific shape are disrupted, causing the protein to unfold and lose its structure. This can result in loss of function and potential degradation of the protein.
Heat which causes a change in temperature of substanceis called?
Heat which causes a change in temperature of substance is called specific heat.
What is the variable that causes change called?
The variable that causes change is called the independent variable. It is the factor that is manipulated or controlled in an experiment to observe its effect on the dependent variable.
Why does protein change colour?
Proteins can change color due to denaturation, which alters their structure and causes them to reflect light differently. This change can be caused by factors such as heat, pH fluctuations, or exposure to chemicals, leading to a change in the protein's appearance and color.
What phase change causes water to evaporate?
This phase change is called evaporation.
What happens to a strand of DNA when there is a change in the base on the other strand?
This is called a "mutation." What ends up happening depends on where the base that changed was located. If the changed base is on the side of the DNA strand that is not used in making mRNA, there will be no difference in the final protein made whatsoever. If the mutation occurs in a part of the DNA that is not coded to make a protein (so called "junk" DNA), there will also be no change in the final protein, because there won't be a protein made. Even if the mutation occurs in a segment of DNA that eventually makes a protein, if the replacement base causes the mRNA to code for an amino acid that is similar to the original base, there will be little change. There is more to it, but that will probably suffice.
How does acids denature proteins?
The Acid disrupts the bonds between the amino acids that make up the tertiary structure of the protein. The disruption causes the protein to denature which causes a change in shape of the protein. We have to realize that sometimes this change in shape is good because the struction deterimines the function.
