Conservationists analyzed DNA samples from over 150 green sea turtles nesting on different isolated beaches. They discovered that despite being separated by thousands of miles of ocean, these populations share a high degree of genetic similarity. Which technique would the conservationists have used to determine the exact order of nucleotides in the DNA and identify these genetic similarities?
Genetic engineering
DNA sequencing
Somatic cell nuclear transfer
Translation
