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.

Some changes wouldn't have any effect on protein, since a few codones are translated to each amino acid, other would change one amino acid in the protein (in most cases the protein would still function, but less effectively) and finaly a change may occure, that completely changes the protein (such mutations makes protein helpless and may cause even death).

When a signal molecule binds to a receptor protein the receptor protein may change the?
shape.
A drastic conformational change in protein in response to conditions such as extreme heat pH will lead to loss of a protein function this drastic change in shape is called?
denaturation
How can changing even one amino acid affect the protein?
changing even one amino acid would change the whole whole sequence hence, change the structure(shape) of the protien because the amino acid ie; the (primary structure) determines the 3 dimensional shape of the protien in the first place,this because the polypeptide posses the positive charge and the negative either side of the peptide bonds these charges form the bonds in the primary-teritary making it into a 3d shape, in conclusion changing one amino acid would disrupt the charges and the way the polypetides are bonded intially changing the protiens structure.

What is the word used to describe the distortion and inactivation of a protein by pH or heat?
Denatured protein. See attached Wikipedia Denatured Protein link. Denaturation. Proteins are fragile and its function depends on its 3D shape. High heat, salt concentration, pH, radiation etc will cause a protein to 'unravel' or change shape which leaves the protein nonfunctional. It is usually irreversible. Think of it as frying an egg. Eggs are protein right? When you fry an egg you change its shape and it is no longer opaque. You cannot unfry an egg.
What determines the sequence of amino-acids in a protein?
The DNA carries the instructions for protein synthesis. These instructions are copied onto mRNA, which then travels to the ribosome. At the ribosome, the mRNA is translated into the correct sequence of amino acids.
How does changing a nucleotide in the DNA code for b-globin change the characteristics of hemoglobin?
Due to change in nucleotide, a completely different protein is coded for. The normal protein has glutamic acid, is hydrophillic; however, the mutated protein incorporates valine, a hydrophobic amino acid instead. This causes the overall haemoglobin protein to distort into a sickle shape, rather than a concave shape. As a result, sickle cells have a much shorter lifespan than their normal counterparts.
Why does changing shape of an object dose not change the density?
Changing the shape CAN change the density. If you change it into a smaller shape, then you increase the density. However the mass will not change.
Does the shape of an object change its density?
Changing the shape CAN change the density. If you change it into a smaller shape, then you increase the density. However the mass will not change.
Is a cloud changing shape a chemical change?
No. it is not. It is a physical change.
How can one amino acid have a great effect?
If you mean how does changing one amino acid have a great effect, that single change may alter the shape of the protein in a critical area, which can make the protein function poorly or not at all.
When a signal molecule binds to a receptor protein the receptor protein may change the?
shape.
Is changing the size and shape of pieces of wood a chemical change true or false?
False. Changing the size and shape of pieces of wood is a physical change because the wood's composition does not change.
Why is it important that a protein keep in shape?
because the shape of a protein allows it to perform its particular job

How does moon's shape and position change over time?
The moon's shape would change with the impact of meteor's, changing the moon's landscape.
Which one is not a sign of a chemical change change in shape bubbling smoking changing color?
A change in shape. If you break something, it's still the same stuff just in a different shape.
