DNA Sequencing – Mapping Genomes

DNA sequencing is the process of determining the nucleic acid sequence in DNA.

Applications of DNA sequencing: mapping species genomes

Complete sequences of genomes (e.g., mouse, fruit fly, cat, dog, ape, and human) allow us to compare the DNA of closely related species in order to establish and analyse their genetic differences, a field known as comparative genomics.

DNA Profiling – Identifying info

DNA profiling is the process of determining an individual’s DNA characteristics.

Applications of DNA profiling: to identify unique genetic information

DNA profiling is a forensic technique in criminal investigations, comparing criminal suspects’ profiles to DNA evidence so as to assess the likelihood of their involvement in the crime. It is also used in parentage testing, to establish immigration eligibility, and in genealogical and medical research.
