What is a missense protein?
A missense protein is a protein translated due to a change in a single amino acid.
Does a DNA mutation always result in a change to the protein?
No, a DNA mutation does not always result in a change to the protein. Some mutations are silent and do not affect the protein's function.
What does motivation for behavior change?
a protein is an
What would happen to a protein if the gene was changed DNA?
If a gene encoding a protein is altered at the DNA level, it can result in a change in the protein's amino acid sequence. This alteration can lead to changes in the protein's structure and function, potentially affecting its ability to interact with other molecules and carry out its normal physiological roles.
How can a mutation in a base sequence cause a change in a protein?
dna in a cell needs protein and chromosomes.
Why the addition of an extra base in a DNA sequence would change the message carried by a DNA molecule?
It could change the type of protein that would be produced hence change the structure and function of that protein.
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 activates a G protein?
G protein is activated when a ligand (such as a hormone or neurotransmitter) binds to a G protein-coupled receptor (GPCR) on the cell membrane, causing a conformational change. This change allows GTP to bind to the G protein, replacing GDP, and activating the G protein to carry out downstream signaling cascades.
How can a mutation in a DNA bases sequence cause a change in a protein?
dna in a cell needs protein and chromosomes.
How can a mutation in a DNA base sequence cause change in a protein?
dna in a cell needs protein and chromosomes.
Can changing just one nucleotide in a gene change the shape of a protein?
If shape of a protein is changed its function is altered. This might change or stop a particular biochemical pathway in which that enzyme was critical. Specific 3D shape of each protein is very essential for its function. Change in shape of proteins is caused by a mutation in the DNA.
