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.
Since bases can only pair with their complement like A with T or U, depending on what phase of replication you are referring to, and C with G, a protein that undergoes a mutation that tries to force a base to pair with a base it cannot pair with will typically signal for apoptosis (programmed cell death) to prevent cancer or another harmful SNP to the organism unless it is recognized to be beneficial, which is extremely rare.

In a point mutation, one nitrogen base is substituted for the correct base. Since most amino acids can be coded for by more than one codon, there may be no consequence to this mutation. However, sometimes a point mutation results in an incorrect amino acid being added to the amino acid sequence of the protein. This can cause a change in the shape and therefore function of the protein, which can be a harmful mutation. Two genetic disorders caused by a point mutation are cystic fibrosis and sickle cell anemia.
A mutation in a gene can happen by addition, deletion or substitution of base pairs. This means that the order of the bases will change- a new base may be added, a base may be lost, or one base may be substituted for another. The result of these mutations is that it causes the DNA to code for a different protein. If a mutation occurs in a sex cell, the mutation can be passed on to an offspring and affect the offspring's phenotype.

When you change one or several nitrogenous bases it produces a change in the function of the protein. The reason why is because the amino acid that is being added to the protein changes due to the change of one of the base. So the shape will change and have a different function.Your Welcome,Anonymous
Because a protein's function is dependent on is shape, and a mutation may change the composition (the sequence of amino acids) of a protein, which may in turn cause the shape of the molecule to change.

Both types of mutation have the potential to cause a large effect.In general, a frameshift mutation is more likely to cause a large effect. This is because it shifts the 'reading frame' - so that all of the subsequent codons (groupings of 3 bases that are read to determine which amino acid will be added) will be changed.A point mutation is when a single base is replaced. This can either result in the same amino acid being added to the protein being synthesised (a silent mutation), a different amino acid being added (a missense mutation) or in a STOP codon (a nonsense mutation).If a point mutation causes a premature STOP codon - this is quite likely to have a large effect on the protein.
Base-pair insertions have a greater effect because they shift the information on the DNA down and change all following information, whereas substitutions may change only one amino acid or have no effect. -The base-pairs code for amino acids in groups of three. If just one base is added in, then this grouping is shifted upstream by one. The incorrect amino acids will be coded for and added to the protein being built. It could possibly stop the protein from being synthesized fully if the change creates a stop codon. This usually hinders the protein from functioning. -Base-pair substitution mutations only affect the codon (set of 3 base pairs) that it actually occurs in. If the mutation is in the first base-pair of the codon then the amino acid will change. If the mutation is in the second or third position of the codon then amino acid may or may not change; this is because amino acids can be coded for by more than one codon, but the first base-pair (and sometimes the second) is usually the same. A substitution can also change a codon to a stop codon. This may keep the amino acid the same, change only one amino acid (which does not always stop the protein from working), or cause the protein to prematurely stop being built.
