dna in a cell needs protein and chromosomes.
This is the phase in which DNA is replicated.
Mutation occurs where one DNA nucleotide base is changed in the process of DNA replication. These mutations may or may not cause genetic disorders or other observable changes in the organism, but they play a huge role in evolution, cancer, and immune system development.

It will depend on how the DNA is altered. If the introns are altered there should be no significant risk to the cell. If a single base is altered, but the codon still produces the same amino acid (silent mutation) - there will be no effect on cell function. A major change to DNA (such as a frame-shift or nonsense mutation) may affect vital protein products and this could lead to cell death.

Mutations can be inherited. This means that if a parent has a mutation in his or her DNA, then the mutation is passed on to his or her children.Mutations can be acquired. This happens when environmental agents damage DNA, or when mistakes occur when a cell copies its DNA prior to cell division.

Cancer- certain mutations (changes) in a cell's genetic material may cause that cell to reproduce with out control.
because if not.. it will cause DNA mutation... your features may change or worst.. it may cause cancer... because in theory.. cancer is caused by DNA mutations...

A mutation is an alteration in the DNA of the cell. Because the mutation is not "part" of the original DNA of your body, it cannot be passed onto your offspring
Mutations (point mutations, inversions, translocations...) cause changes in DNA Simply stated, a mistake made while DNA copies causes changes in DNA.
UV rays. These cause thymine to form dimers in skin cell DNA.
Each new cell needs a copy of the original cell's DNA to ensure that it has the same genetic information necessary for carrying out cellular functions and processes. This DNA contains instructions for the cell's development, growth, and functioning, so having an accurate copy is essential for the new cell to properly function and divide.
