In part 1 of this lesson, students learn the basics of dna profiling, including the structure and inheritance of strs. Dna fingerprinting relies on the fact that the dna code is universal for all living things and that there are differences between individuals within that code. A standard curve is a tool that allows forensic scientists to estimate the size of dna fragments of unknown samples by comparing them to standards with known dna fragment sizes.
