Yes, but error rates are very low. Usually about 1 in 100,000 nucleotides or better. Errors occur more when there are long sections of matching nucleotides called repeats. The polymerase can "hiccup" and read a nucleotide again or skip over it. There are enzymes that check for correct sequences as well. They are either part of the polymerase complex or come along and look to make sure the new and old match.
One error occurs for every billion paired nucleotides added.
They occur about 1 in every 300,000 people so about .0001 chance
Yes errors can occur especially if splicing is involved. Mutations in DNA also happen during cell division (both meiosis and mitosis).

You DNA will be replicated
Interphase is when DNA replication occurs. :)
DNA is replicated in the process called Mitosis and Meosis. DNA is replicated to make more cells. Your body will make cells if you have a cut, grow, etc..
in the nucleus
yes
the DNA poly-meres must add complementary nucleotides to the DNA
DNA polymerase replicated DNA. RNA polymerase creates mRNA to be used in protein synthesis. RNA polymerase does not replicated DNA.
They include: incorrect copying of the DNA sequence when the DNA is replicated before division, and errors during recombination. If an error occurs in a sperm or an egg, the individual created from that gamete will have the change in every cell of their body.
DNA is replicated in the S phase of Interphase
The cell's DNA is replicated during interphase.
DNA replication must occur before cell division to make sure that the daughter cells are genetically identical.
What is DNA replicated before?
