List three ways that DNA technology could be used to improve the lives of humans?
1. Identify humans 2. Identify human remains 3. Trace human origins
How do scientists use DNA to study the origins of human?
houg
Can you trace your Indian ancestoral roots?
If you are speaking of your American Indian roots, to trace the origins it might be possible by using DNA. It would even be more help if you have relatives and they would give their DNA as well.
How was blood used for forensics?
It is used to trace DNA.
How is the mitochondrial DNA useful in identifying people?
Mitochondrial DNA is passed in an unbroken line from mother to offspring. The father does not contibute mt DNA to his children. Any changes in DNA sequences builds up gradually from mutations only. These mutations can be compared across populations for differences and simarlarities and therefore trace movements and ancestry of human populations. This removes any confusion that arises from nuclear DNA in which is a mixture of both parents and so changes with every generation. One exception for this is Y chromosome DNA which is passed in an unbroken line from father to son and can be used in a similar way as analysing mt DNA but only for males.
Human chromosomes have hundreds of where the dna is unzipped so replication can begin?
origins of replication
What are two different uses of DNA fingerprint?
The DNA fingerprint is used in many fields. DNA fingerprints are commonly used in forensic science. Also, the Human Genome Project utilized DNA fingerprints to map the entire human genome.
What type of DNA traces female lines back into the deep past?
The mitochondrial DNA can be used to trace female lines of descent.
Can DNA Fingerprinting be used for indicating plant pathogens?
yes it can. they trace the DNA of the plant, if in the plant DNA found a sequence resemble to a virus DNA or rna, the plant been infected with pathogens.
Why were garden peas used in studying genetics?
because their DNA are similar with the human DNA.
What are the areas on DNA where replication occurs called?
DNA replication begins in areas of DNA molecules are called origins of replication.
What enzyme is used to unzip DNA?
The helicase enzymes are used to unzip DNA. There are 31 specific DNA helicases. There are 95 unique helicases in the human genome.
