If one amino acid in a protein sequence is changed what could happen?

sometime nothing- If the substituted amino acid (AA) is chemically similar (in terms of polarity, acid/base, size) to the original, the protein might be able to function without problem.
However, if the substitution is to a very different AA, then drastic changes can occur. If the wrong AA is sequenced, then the protein might misfold (improper tertiary structure, tertiary structure is determined by primary structure- sequence of AA). If you get a misfolded protein, it might not function as well or at all.
Note that Sickle Cell Disease is caused by a Valine-Glutamine substitution. This results is a misfolded hemoglobin that causes the RBCs to "sickle". Thus, this reduces their oxygen carrying capacity.

When a nitrogenous base is inserted or delete how does that affect the amino acid sequence?
The amino acid sequence is shifted, and this kind of mutation is called a frame shift mutation. All of the amino acid sequence after the mutation will be changed, which will cause a change in shape of the protein, which will then probably result in a nonfunctional protein, since the shape of a protein determines its function.
What is primary structure of a protein and what causes it?
Primary structure of the protein is simply its amino acid sequence. It is the sequence in which amino acids are added during protein synthesis.
Does amino acids affect protein functions?
The sequence of amino acids affects protein function. The three-dimensional structure of a protein determines its function. The three-dimensional structure of a protein is determined by the sequence of its amino acids.
What sequence best represents the relationship between DNA and the traits of an organism?
DNA base sequence amino acid sequence protein shape protein function trait
The sequence of nucleotides in DNA specifies the sequence of what in a protein?
Amino Acids

What determines the amino acid sequence in a protein?
The sequence of amino acids in a protein is determined by the sequence of nucleotides in the mRNA, and this is determined by the sequence of nucleotide bases in the DNA.
Which structure determines the sequence of the building blocks in a protein?
DNA determines the sequence of the amino acids (building blocks) in a protein. The sequence of nitrogen bases in the DNA determines the sequence of amino acids in a protein.
What is primary structure of a protein and what causes it?
Primary structure of the protein is simply its amino acid sequence. It is the sequence in which amino acids are added during protein synthesis.
What influences protein shape that determines protein function?
Amino acid sequence primarily determines a proteins shape, but secondary (alpha helix and beta sheet) and tertiary structures (Hydrogen bonding, other chemical bonding between structures) adds to it.
Specific function of a protein is determined by?
exact sequence of amino acids
Does amino acids affect protein functions?
The sequence of amino acids affects protein function. The three-dimensional structure of a protein determines its function. The three-dimensional structure of a protein is determined by the sequence of its amino acids.
The sequence of amino acids joined together refers to the?
Peptide sequence or amino acid sequence is the order in which amino acid residues, connected by peptide bonds, lie in the chain in peptides and proteins. The sequence is generally reported from the N-terminal end containing free amino group to the C-terminal end containing free carboxyl group. Peptide sequence is often called protein sequence if it represents the primary structure of a protein.
What sequence best represents the relationship between DNA and the traits of an organism?
DNA base sequence amino acid sequence protein shape protein function trait
How do proteins differ from one another in the number and sequence of amino acids?
the sequence of amino acids in the polypeptide chain differs from protein to protein -xbanditlover
The sequence of nucleotides in DNA specifies the sequence of what in a protein?
Amino Acids
The sequence of amino acids that makes up a protein molecule is determined by the sequence of?
The primary structure of a protein is the sequence of amino acids in the protein. This is determined by the sequence of bases in the DNA ie by the genetic code. Each group of three bases in DNA codes for one amino acid in the protein ie it is a triplet code.
