Paternity Testing, Identifying Tendencies for Diseases, & Treating or Curing Genetic Diseases
The structure of DNA is known as a double helix. The helix contains approximately ten nucleotide pairs per helical turn. Each spiral strand, is unique to an individual and this can be used to identify individuals. The uniqueness of DNA allows for people to be identified through paternity testing and has the benefit of revealing defective genetic traits that are found in diseases such as certain cancers. In most instances, DNA can identify individuals in a high probability of 98% or more (Elkins, 2013).
DNA fingerprinting which is also known as DNA profiling is a method of recording DNA in images which forensic scientists can use to compare with crime scenes to make identification of victims and offenders. DNA finger printing is controversial because many people believe it is an invasion of privacy. However, DNA finger printing is more exact of a science of identification and has already helped to free many prisoners who were wrongly convicted.
