Werner's syndrome is a rare genetic disorder primarily caused by mutations in the WRN gene, which is involved in DNA repair and maintenance. While it is not directly caused by DNA disintegrating, the dysfunction in the WRN protein leads to genomic instability, accelerated aging, and increased susceptibility to age-related diseases. This impaired DNA repair mechanism contributes to the cellular and tissue abnormalities seen in individuals with the syndrome.

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
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)
Is DNA RNA OR DNA?
Elephantiasis is caused by a microfilarial nematode (very small worm).
What is a change in DNA sequence caused by a mistake in DNA replication or exposure to radiation or chemicals called?
A change in DNA sequence caused by a mistake in DNA replication or exposure to radiation or chemicals is called a mutation. Mutations can lead to variations in genes and can sometimes result in negative effects on an organism's traits or health.
What is variation caused by?
It is caused by crossing over in sexual reproduction and random mutations in DNA.
Where did down syndrome come from?
Downs syndrome is a genetic abnormality caused by an extra chromosome, in simple terms - as a healthy individual you inherit 22 chromosomes from your mother and 22 from your father, so that's 44 altogether, 1 chromosome from each of your parents will combine to form 22 sets, in a person with Downs syndrome there is an extra abnormally shaped set of chromosomes. So in short a person with Downs syndrome has 23 chromosomes instead of 22.
Can human DNA chromosomes be artificially removed to prevent genetic or hereditary diseases like removing the extra chromosome 21 which causes down syndrome?
Currently, there is no safe or effective way to artificially remove entire chromosomes from human DNA to prevent genetic or hereditary diseases. Down syndrome, for example, is caused by an extra copy of chromosome 21, and simply removing this extra chromosome would be complex and could have unintended consequences. Research is ongoing to develop therapies that may one day help manage genetic conditions like Down syndrome.
