DNA found in the nucleus of a cell. The nucleus is the cell's control center. Nuclear DNA contains the entire genetic make-up of a person, including inherited traits such as eye color or height. There is only one group of nuclear DNA per cell, since each cell has only one nucleus. Since nuclear DNA is sensitive to environmental conditions, it can be difficult to obtain useable nuclear DNA from deteriorated and/or old crime scene samples. The alternative to nuclear DNA analysis is mitochondrial DNA analysis.

The DNA contained in the chromosomes within the nucleus of eukaryotic cells. The nuclear genome in Pacific salmon is approximately 4.6 billion base pairs in size.

DNA found in the nucleus of a cell. DNA testing using RFLP, DQA1 (DQa), PM, D1S80, or STRs screen markers in nuclear DNA.
