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.
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.
To create a DNA fingerprint, a scientist would typically extract genetic material from the cell's nucleus, which houses the DNA. The nucleus is the organelle responsible for storing and protecting the cell's genetic information. By isolating the DNA from the nucleus, the scientist can analyze the unique patterns and sequences that constitute an individual's DNA fingerprint.
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.
The scientist who established the structure of DNA was James Watson and Francis Crick.
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.
To find DNA a scientist must look inside a cell's nucleus.
To create a DNA fingerprint, a scientist would typically isolate the nucleus of a cell, as it contains the cell's genetic material (DNA). However, it's important to note that the nucleus is not an organelle that can be "removed" in the traditional sense; rather, the DNA is extracted from the nucleus. Other organelles, such as mitochondria, also contain DNA, but for most DNA fingerprinting purposes, nuclear DNA is the primary focus.
The scientist who helped determine the shape of DNA was James Watson, along with Francis Crick.
Yes, because each DNA is unique and and the scientist can just match the DNA up with andother DNA.
F, Crick and j.Watson discovered the structure of DNA.
