What do forensic scientist use to identify people?

Forensic scientists use various methods to identify people, including DNA analysis, fingerprint analysis, dental records comparison, and facial recognition technology. These techniques help in establishing the identity of individuals for legal and investigative purposes.


How might a forensic scientist use DNA fingerprint?

A forensic scientist can use DNA fingerprinting to identify individuals by analyzing unique patterns in their DNA. This technique is often used in criminal investigations to match a suspect's DNA to evidence left at a crime scene. DNA fingerprinting can also be used to establish paternity or identify human remains.


What should scientist do to find gene that produces protein after he located all the mrna produced by liver and cdna if he wants to artifically produce protein that is produced in liver of frogs?

The scientist should use the cDNA library to sequence the mRNA and identify the gene responsible for producing the protein in the frog liver. By comparing the mRNA sequences to known frog liver proteins, the scientist can pinpoint the gene of interest. Once identified, the scientist can use recombinant DNA technology to express the gene and produce the protein artificially.


What is a example of an advance in DNA technology that has directly affected agriculture?

One example is the use of CRISPR gene editing technology to develop crops with improved traits such as disease resistance or increased yield. This technology allows for precise modification of plant genomes, leading to the development of genetically modified crops that can better withstand environmental stresses and pests.


Why did DNA technology lead to more uso of cladistics?

DNA technology allowed scientists to compare genetic information between organisms, providing a more accurate way to determine evolutionary relationships. Cladistics relies on this genetic data to create phylogenetic trees, leading to a more reliable and detailed understanding of evolutionary history. As a result, the use of DNA technology has increased the use of cladistics in biological classification and evolutionary studies.
