What is the malfunctioning organelle associated with Pearson syndrome?
Pearson marrow-pancreas syndrome is caused by single, large deletions of mtDNA (the DNA found in the mitochondria), which can range from 1,000 to 10,000 DNA building blocks (nucleotides). The mtDNA deletions involved in Pearson marrow-pancreas syndrome result in the loss of genes that provide instructions for proteins involved in oxidative phosphorylation.
Is human DNA in the sewer systems or does it dissintergrate?
Human DNA does sometimes stay alive in sewer systems without disintegrating. However, over time, it will eventually decay. Most times, this can take up to 1 year.
How is Fragile X syndrome detected?
By a DNA blood sample
A change in DNA sequence caused by a mistake in DNA replication or exposure to radiation or chemicals?
A change in DNA sequence caused by a mistake is called a mutation.
What is a change in DNA sequence caused by a mistake in DNA replication or exposure to radiation or chemicals called?
A change in the DNA sequence caused by a mistake in DNA replication or exposure to radiation or chemicals is called mutation.
Do people with aspergers syndrome have more complexe DNA than normal people?
No.
Why chromosomal analysis is needed for bone marrow and fragile X-syndrome determination?
"Chromosomal analysis" should not be used for Fragile X Syndrome determination. Chromosomal analysis, Karotyping, has proven unreiable in diagnosis. Detemination can be made through DNA testing for Fragile X Syndrome, FMR1 DNA test.
What genectic disorder does Down syndrome involve?
Down Syndrome is when there is an extra chromosome in someones DNA. More exactly it is when the 21st chromosome has an extra one.

When 1 strand of DNA becomes 2 this is known as what?
Retardation / Mutation (Down Syndrome)
What is variation caused by?
It is caused by crossing over in sexual reproduction and random mutations in DNA.
What is the change of DNA sequence caused by a mistake in DNA replication or exposure to radiation or chemicals?
Mutation
