Codons are groups of three bases in the messenger RNA (mRNA). Each codon specifies one and only one amino acid when it's time for translation. However, each amino acid can be coded for by more than one codon. After DNA is transcribed to make mRNA, the mRNA is translated to proteins by the ribosome. This is when the codons are important: the ribosome displays the mRNA's codon, and the matching tRNA (transfer RNA) - that is, the one with the complementary anticodon - comes along. The tRNA has the amino acid that is coded for by the codon.
Mitosis is the process by which a cell divides into two, producing two cells that are exactly the same as the parent cell, in terms of DNA. (Cytoplasmic elements may be different. That's okay, because the DNA has instructions for making more proteins.) Mitosis is useful in growth and repair. For example, as an embryo is growing, its cells undergo rapid mitosis, and the fetus gets larger and starts to differentiate into organs. Repair processes occur after an injury, as when you get a cut. Skin cells must undergo mitosis in order to repair what was scraped off. However, not all cells can undergo mitosis - many nerve cells are not able to do so.
They don't really relate. Mitosis has to do with reproduction of a cell, whereas codons have to do with expression of the genes. I guess you could say that, after mitosis, the cell will need more cytolplasmic elements like the endoplasmic reticulum, golgi apparatus, mitochondria, etc. So, after replication, genes are expressed in order to make these structures - and thus the codons would be used.

A codon is a set of three nucleic acids which code for an amino acid- it helps when producing proteins.
Mitosis is the reproduction of somatic cells.

Well, when cells reproduce, everything within needs to be duplicated- including proteins, so codons might be a bit important there.

Mitosis is when a cell prepares itself to duplicate and a codon is the genetic code which is the set of rules by which information encoded in genetic material (DNA or RNA sequences).

a codon consists of 3 consecutive nucleotides that specify a single amino acid that is added to the polypeptide. or a codon is a group of 3 nucleotides on messenger RNA that specify a particular amino acid.
