DNA contains specific physical characteristics unique to the person to which the DNA belongs. This information helps classify organisms, by type. All sorts of traits are used to classify organisms, but DNA is the best way.

If they are less similar, they will be less closely grouped. For example, the genes of humans and chimpanzees are between 95-99% identical, so they are closely grouped together.

What type of characteristics are used to classify organisms today?
In the past, classification relied on body structure, internal and external, as well as mode of reproduction. The change now is that scientists are using DNA to fine tune classification.

Scientists can tell whether organisms are closely related by comparing their?
Scientists can tell whether organisms are closely related by comparing their DNA. This will allow then to look at various traits and features so as to compare the relationship between organisms.
How is DNA extracted from fossils what are the costs associated with testing DNA in fossils?
Fossils are the mineralised remains of organisms and contain no organic material.
Where do organisms get their DNA?
every organism comes from parents through the process of
How do biologists use DNA and RNA to help classify organisms?
DNA and RNA shows how similar or different the organisms are, so you can group them into categories based on how similar they are to one another.
How do biologist classify organisms?
In basic terms: biologists classify organisms by species, genus and family.
How are DNA and biochemical analysis and embryology and morphology used to classify organisms?
Who cares.they have in common the classification and name.
What two things are required to classify an organisms?
Morphology and taxonomy are used to classify organisms and now DNA studies are part of it.
How did DNA help classify the platypus?
DNA help classify the platypus because with out it the DNA the platypus would be classified with the marsupials which would be wrong.
How does DNA lead scientists to better classify organisms?
So is
What criteria do scientists use to classify organisms?
They are classified according to the DNA they share with other organisms.
What allows scientists to use genetic information to classify organisms?
DNA is the answer.
Taxonomy in molecular biology?
Analyzing DNA and other parts of the cell helps to classify organisms.
Scientist classify organisms based on what?
structural likenesssimilarities in DNA sequencesimilarities in embryonic stages of development
What kind of information do scientist use to classify organisms?
Taxonomists use fossil records, morphological structures, and DNA/genetic information in order to classify organisms into different kingdoms, phylums, and classes.
Why is it hard to classify extinct organisms using only fossil evidence?
Because scientists can not obtain the complete DNA of the extinct animal
