Basically change in the DNA sequence of a gene is associated with change in the nucleotide sequence which may result in Mutation and may cause loss of function of that particular mutated gene.
This would result in a frameshift mutation. This would cause the protein, after translation, to be truncated and would most likely be non-functional. This is due to a change in the amino acid sequence and would stop the protein from forming the correct secondary and tertiary structures due to a change in the electrostatic/ hydrophobic/ h-bonding etc. parameters of the protein
It depends. Because many amino acids have more than one codon, it may not affect the protein at all. However, if it does change the amino acid sequence, it could cause a change in the three-dimensional structure of the protein, resulting in a mutation.
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.

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.
A frameshift mutation may cause a change in the codon sequence, specifically the 3-base sequence which is responsible for coding a specific amino acid. A different protein, a non-functional one, or no protein at all may be the result of this change.
Mutation usually causes the entire base sequence to defect. This usually happens during the protein synthesis.

mutation: a change in the sequence of DNA to cause a unusal trait
A mutation in which an extra nitrogen base is added is called a frameshift mutation. The rest of the sequence after the mutation will code for different amino acids, which will result in the alteration of the protein. Frameshift mutations cause severe genetic disorders.
a chnge in the sequence of base pairs
Many times a change in the base sequence during DNA replication will cause a mutation but if it is the 3rd base often there will be no mutation . It will often give the same protein. The term is genetic "wobble" and is seen when mRNA and tRNA match do not match at the third base.
Cancer- certain mutations (changes) in a cell's genetic material may cause that cell to reproduce with out control.
