How does someone get a genetic disorder?

I understand that transcription of DNA is and that this is where mutation occurs. What would make this mutation phenotypically represented? What are the processes of substitution, addition, and deletion in genetic mutations? How do they effect the sequence of the DNA and the amino acids eventually translated into a protein chain?

Are you asking for assistance with a homework assignment?
@Jeruba – No. I’m just really curious about this. I love biology a lot.
Generally a single gene mutation doesn’t cause a genetic disorder. You get a genetic disorder if both your parents were carriers, and you got the bad alleles at all the right (wrong) loci.
Ok, I might be being dense here but:
“How do they effect the sequence of the DNA and the amino acids eventually translated into a protein chain?”
Genetic disorders are written into the DNA. They are not affected by DNA, they are in the DNA string itself just like eye color, hair color, etc. They change as mutations occur naturally and are reinforced by breeding with people who carry the same traits. Over time, a lot of it, what is known as a genetic disorder evolves.
Here is an example of disorder via genetic studies in an ethnicity (mine because it is handy).
Genetic disorders evolve just like all other genetic traits.
Someone gets a genetic disorder if it is in your ancestry usually. If your parents, aunts, uncles have a condition that can be passed down thru dna. Sometimes there are genetic accidents due to drugs, disease, toxins, or something unknown.
Oh I had forgotten how good the link I provided above is but, if you really want to get your teeth into genetic disorders in general, that is an excellent start. It focuses on my people but the principles of it can be applied to anyone.
The site is Bio Med Central, the section is BMC Medical Genetics.
I suspect that somewhere on that site is the basics of genetics. I have not dug through it yet.
@Oxymoron Not rude. You expect to gain the knowledge equivalent to several college courses here? An inquiry for something this broad calls for research—not a question/answer site.
@thriftymaid – It doesn’t take years in college to find this out. After I asked it I learned about this the next day in first year biology course. I didn’t need someone to give me a five page answer or something.
