Does DNA replication occur in cell division? One characteristic of the DNA molecule is its replication capability. What are the consequences of failures during DNA replication?

Yes. DNA replication occurs in mitosis as well in meiosis. 

Ideally a DNA molecule should replicate in a perfect way. Sometimes however failures in the duplication occur, with alteration (deletion, addition or substitution) of one or more nucleotides in the molecule. Those mistakes, or mutations, therefore make changes in the protein synthesis process too. For example, the production of an important protein for cells or tissues may be suppressed, new utile or inutile proteins can be created, etc. The mistake in the DNA duplication and the resulting production of altered genetic material are some of the main creative forces for the biological evolution and the diversity of species.
