What else can I help you with?
Does evolution determined using similarities in DNA and branching trees?
Yes, evolutionary relationships can be determined by comparing similarities in DNA sequences and constructing branching tree diagrams to represent the relatedness of species. This approach, known as phylogenetics, uses DNA evidence to infer the evolutionary history of organisms.
How can one create a phylogenetic tree from DNA sequences?
To create a phylogenetic tree from DNA sequences, scientists use bioinformatics tools to compare the genetic information of different species. They analyze the similarities and differences in the DNA sequences to determine evolutionary relationships and construct a branching diagram that represents the evolutionary history of the organisms.
What evidence do scientists use to create branching tree diagrams?
Scientists use evidence from comparative anatomy, fossil records, embryology, and molecular biology to create branching tree diagrams, also known as phylogenetic trees. These diagrams help to illustrate the evolutionary relationships between different species and how they have diverged from a common ancestor over time.
What scientist established the structure of DNA?
The scientist who established the structure of DNA was James Watson and Francis Crick.
Why do scientist isolate DNA?
Scientists isolate DNA to study its structure, sequence, and function. By isolating DNA, scientists can analyze specific genes, create genetic maps, and understand how genes contribute to traits and diseases. Isolating DNA also allows for techniques like PCR and DNA sequencing to be performed.
Were must a scientist look to find DNA?
To find DNA a scientist must look inside a cell's nucleus.
Which scientist helped to determine the shape of DNA?
The scientist who helped determine the shape of DNA was James Watson, along with Francis Crick.
Can a scientist tell from DNA result alone what type of DNA sample were used in the test i.e. is it from blood or semen sample?
Yes, because each DNA is unique and and the scientist can just match the DNA up with andother DNA.
Who was the scientist who did the structure of DNA?
F, Crick and j.Watson discovered the structure of DNA.
Which scientist studies human DNA?
CARTIOTOLIJIST
What can make up DNA?
nothing can make DNA, DNA is very unique. all though scientist are working on and have cloned DNA.
What kind of scientist studies human DNA?
a geneticist
