The addition or deletion of a nucleotide can lead to a Frameshift mutation. The Frameshift mutation causes a "shift" in the reading frame of the codons in the mRNA. This may lead to the change in the amino acid sequence at protein translation.
Mutation can occur as a result of a change in the sequence of nucleotides in a strand of DNA.

During DNA replication, the enzyme DNA polymerase catalyses the formation of new strands of DNA, using the old strands as models. DNA has a double-helix structure, with two strands forming each helix. Each strand is made up of DNA nucleotides, with the genetic information encoded in the sequence of different nucleotides (different nucleotides are distinguished by molecules called 'bases' attached to them, so the sequence of nucleotides is known as the 'base sequence'). The base sequence of one strand is complementary to that of its' neighbour - the base A binds with T, and C with G, so if one strand had the sequence ATTACA, the base sequence of the complementary strand would be TAATGT. When DNA polymerase creates a new DNA strand, it does so by matching nucleotides to the base sequence of one of the strands - the template strand. New nucleotides are brought in, which match the template in a complementary fashion (ie. A-T, C-G), and join to become one new strand. This new strand is complementary to the template.

The sequence of nucleotides of the complementary strand will be the nucleotides which bind to the nucleotides of the template. In DNA, adenine binds to thymine and cytosine binds to guanine. The complementary strand will therefore have an adenine where the template strand has a thymine, a guanine where the template has a cytosine, etc. For example: If the template strand is ATG-GGC-CTA-GCT Then the complementary strand would be TAC-CCG-GAT-CGA
A complimentary DNA sequence is the genetic code on the partner strand that aligns with and corresponds to (matches) the code on the primary strand. Each nucleotide has a match, A matches T and C matches G, therefore the complimentary sequence for ATCGA is TAGCT.

They bond, and make a replication of itself.
G=C, G=C, T=A, A= T So, to answer the question: CGGTAAC

Yes because the bases pair uniquely when the strands are joined together.
The sequence of nucleotides is altered and therefore, the amino acid that is to be added to the peptide chain will be altered. hence the protein will be different. This protein can be functionless (will be degraded). If it turns out to be toxic, then there may be symptoms.
Each of these letters stands for a base (which is part of one nucleotide). Therefore because there are 12 bases, there would be 12 nucleotides in the strand.

No, DNA, from difference with the RNA, is a double strand of nucleotides. DNA, double strand (hence the double helix nickname). RNA, single strand.
Yes, strands of DNA are complementary. Complementary implies that a sequence of nucleotides (ex. ATATG) is ordered in a way that it directly corresponds to another sequence of nucleotides (ex. TATAC). Since DNA is double stranded in most circumstances, barring mutagenesis, one strand would be pair with its complementary strand, thus forming the double stand.
