The sequence of the nitrogenous bases changes (and sometimes some bases are added to the sequence or completely removed).
The nucleotide sequence is altered, thus changing the sequence of the mRNA codons. This causes the wrong amino acid to be produced resulting in a non-functional polypeptide. Occasionally, there is no effect or the protein is actually improved.
Sickle-cell disease and Cancer are both results of mutations. The nucleotide sequence is altered, thus changing the sequence of the mRNA codons. This causes the wrong amino acid to be produced resulting in a non-functional polypeptide. Occasionally, there is no effect or the protein is actually improved.

the genetic characteristics would be changed (chromosome, genome pattern could be changed/modified).
In worst cases mutation could raise to many diseases...like auto immune diseases, cancer etc.
Wow, several different approaches to this Answer: One, for sure is when the primary Sequence of Dna is Altered, so is It's pattern of Expression also altered. This Results in Altered 'Patterns of Expression', and altered Protein Products.
The most significant Follow-up is: How do the Dna mutations, reflected in and through altered protein products, significantly Affect the Cell's functions.
If there is a mutation in your body (somatic) cells after you're born, it depends on where the mutation is and what it might interfer with. The body has a built-in system to protect us against harmful mutations. Generally you won't see any change even if the mutation can't be corrected. And consider how many somatic cells you have. The problem comes when the mutation is in your sex cells because that is the DNA you contribute to your children, and there is very little room for error.

There are a number of things which happen to DNA when a mutation occurs. The DNA information is replicated and copied to the new cells which are generated.
The persons cells might stop dividing in life!
Sex cells
This is because body cells do not contribute genetic material to sex cells.
A mutation in a sperm or egg cell means that the mutation while most likely be passed down to the offspring of that organism. If the mutation is in anything but a gamete, it will not be passed down.
They get out of your body by your feces
Mutations in sex cells can be passed on to children. Mutations in sex cells only affect offspring. Mutations in sex cells do not affect the organism.
Question not clear.
Sex cells
A mutation in a sex cell may be passed on to an offspring. A mutation in a somatic (body) cell cannot be passed on to an offspring, but can potentially cause cancer in the person who has the mutation.

No, it can't, not to my knowledge anyway. cancer is a mutation of healthy cells into cancerous cells. its not a virus or bacteria that is foreign to the body. it is a mutation of your body. I may be remembering my info wrong though
Generally, a germ line mutation or sex cell mutation. Could be anything from a point mutation, one amino acid difference, to a whole frame shift mutation.
No. As long as the mutation does not occur in the reproductive cells (sperms or ovum), it will not be pass on to the offspring.
Once a sperm fertilizes an egg, division begins to occur very rapidly so a mutation from either of those cells will affect any of the daughter cells. Sperm and egg cells are undifferentiated, meaning they are able to turn into any type of cell in the body. So a mutation in either the egg or sperm could potentially travel to every part of the body. Heart cells are differentiated (specialized) and are only able to divide into that type of cell, so a mutation in a heart cell will only stay in that area of the body.
For a mutation to be passed onto the next generation it must be on sex chromosome. If mutation occurs in somatic cells of our body, it will not be passed on to the offspring(s). Mutation that changes one or few base pairs in the DNA is called point mutation.
