What else can I help you with?
In cystic fibrosis a change in a single gene causes the protein called CFTR to?
fold improperly
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.
How can small change in the DNA of a cystic fibrosis patient cause the disease?
Cystic fibrosis is primarily caused by mutations in the CFTR gene, which encodes a protein responsible for regulating salt and water movement across cell membranes. A small change, such as a deletion of three nucleotides, can lead to the production of a malfunctioning protein that disrupts this regulation. This dysfunction results in thick, sticky mucus buildup in various organs, particularly the lungs and pancreas, leading to the characteristic symptoms of the disease. Thus, even a minor alteration in the DNA can have significant physiological consequences.
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.
Suppose part of an amino acid sequence of a protein changed from tyrosine proline glycine alanine to tyrosine histidine glycine alanine this change was most likely caused by a point mutation called?
This change was most likely caused by a point mutation called a missense mutation. Missense mutations involve the substitution of a single nucleotide in the DNA sequence, leading to a change in one amino acid in the protein sequence. In this case, the substitution of a single nucleotide led to the change from tyrosine to histidine in the protein sequence.
Can a change in a nucleotide cause a disease?
By changing a gene's instructions for making a protein, a mutation can cause the protein to malfunction or to be missing entirely. When a mutation alters a protein that plays a critical role in the body, it can disrupt normal development or cause a medical condition. A condition caused by mutations in one or more genes is called a genetic disorder. So, yes.
What is it called when there is a change in the three-dimensional shape of a protein?
It is called "Denaturing" of proteins.
What is a physical change in matter caused by a loss or gain of heat called?
A physical change in matter caused by a loss or gain of heat is called a thermal change.
What is the term used for a change in a protein's three dimensional shape or confirmation due to disruption oh hydrogen bonds disulfide bridges or ionic bonds?
The term for a change in a protein's three-dimensional shape due to disruption of hydrogen bonds, disulfide bridges, or ionic bonds is called denaturation. This process can be caused by factors such as heat, pH changes, or chemicals, leading to loss of protein function.
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 is the permanent change in the structure of a protein?
A permanent change in the structure of a protein is known as denaturation. This alteration disrupts the protein's native shape and can be caused by factors such as heat, pH changes, or chemical exposure, leading to loss of function. Denaturation is usually irreversible.
Milk curdles when lemon juice is added to it. The change that occurs in the protein is called?
It is called denaturation
