Down's syndrome is caused by trisomy of the 21st chromosome. This is mostly caused when the chromosome pair fails to separate properly (nondisjunction).

The process that result in Down syndrome is called?
Nondisjunction
When a mistake happens in the process of copying DNA the result is called .?
When a mistake happens in the process of copying DNA, the result is called a Mutation.
Is down syndrome the result of a mutation on a gene?
No. It is due to a third chromosome (21) instead of just the normal two.
A chance mutation causes a cheetah to be born with very short front limbs What will be the most likely result of this mutation?
The cheetah will not be able to run as fast.
Is natural selection a process or a result of a process?
Natural selection is only the result of changing environments, mutation and the variation resulting therein. Natural selection is the process of adaptive change and the main mechanism of evolution that leads to speciation. Natural selection is a process as mutation and variation are grist to the mill of natural selection.
Causes Down Syndrome?
Having an extra copy of chromosome 21. You are supposed to have 2; when you have 3 (trisomy 21), Down's Syndrome is the result.
What can occur as a result of a change in the sequence of nucleotides in a strand of DNA?
The addition or deletion of a nucleotide can lead to a Frameshift mutation. The Frameshift mutation causes a "shift" in the reading frame of the codons in the mRNA. This may lead to the change in the amino acid sequence at protein translation.
Is down syndrome a mutation?
Down Syndrome is caused by extra genetic material on Chromosome 21. About half of the children of people who have Down Syndrome are born with Down Syndrome themselves. See the Related Linksbelow to view an article about the genetics of Down Syndrome.
What are the causes of malabsorption syndrome?
A fault in the digestive process may result from failure of the body to produce the enzymes needed to digest certain foods. Congenital structural defects or diseases of the pancreas, gall bladder, or liver may alter the digestive process.
How is a mutation harmful to a organism?
Not all mutations are harmful. A mutation the give the organism antibiotic resistance, for example, is quite helpful. A different mutation that causes a necessary protein to misfold may result in death. In general mutations that affect proteins that are necessary for life will result in the death of the organism. One such mutation is in the protein p53 which is necessary to prevent a cell from growing uncontrollable (cancer). A mutation in p53 could result in a cell with damaged DNA to reproduce - this is what we call cancer.
What are mutation that result in death?
These are called fatal genetic mutations. Same examples are: Tay-Sachs disease, Neimann-Pick disease, Trisomy 18 and Trisomy 13 are "Edwards Syndrome" and "Patau Syndrome," respectively and Cystic fibrosis
As a result of the incorrect sequence of amino acids will be translated into a protein-resulting in a mutation?
Missence mutation
