Nuclear DNA is a nucleic acid, a polymeric biomolecule or biopolymer, found in the nucleus of eukaryotic cells. Its structure is a double helix, with two strands wound around each other, a structure first described by Francis Crick and James D. Watson (1953) using data collected by Rosalind Franklin. Each strand is a long polymer chain of ...
Oct 8, 2018 · Genetic analysis is a fundamental tool in the positive identification of skeletonized remains. However, choosing the appropriate genetic test depends upon the specific question that needs to be addressed, the ability to obtain a reference sample, and the condition of the DNA sample. Human cells contain two types of DNA: nuclear and mitochondrial.

Jan 1, 2022 · Nuclear Forensics is an important element in a state's nuclear security architecture and serves to address the threats of nuclear smuggling, nuclear proliferation and nuclear terrorism. The aim of a nuclear forensic examination is to obtain information on the processing history of the material (including its method and date of production) and ...
Mar 25, 2024 · The uses of routine nuclear DNA profiling within forensic science are multi-dimensional, providing value to investigations and for intelligence purposes. DNA profiling, as noted previously, is highly discriminatory and can be used for the identification or exclusion of persons related to crimes.

Sep 9, 2021 · Abstract. The analysis of DNA from biological evidence recovered in the course of criminal investigations can provide very powerful evidence when a recovered profile matches one found on a DNA database or generated from a suspect. However, when no profile match is found, when the amount of DNA in a sample is too low, or the DNA too degraded to ...

Nuclear forensics is the investigation of nuclear materials to find evidence for the source, the trafficking, and the enrichment of the material. The material can be recovered from various sources including dust from the vicinity of a nuclear facility, or from the radioactive debris following a nuclear explosion .
Nuclear DNA: Nuclear DNA (nDNA) is the most discriminating and is typically analyzed in evidence containing body fluids, skin cells, bones, and hairs that have tissue at their root ends. The power of nDNA testing lies in the ability to identify an individual as being the source of the DNA obtained from an evidence item, or by excluding an ...
