options: exon, somatic cells (body), allele, nuclear dna, gene

Explanation:

Each definition is matched to the corresponding biological term based on standard genetics and cell biology vocabulary:

1. Nuclear DNA is specifically the DNA housed in a cell's nucleus.
2. Somatic cells are the body cells of humans, containing all DNA except sex-determining chromosomes.
3. Exons are the coding, expressed portions of a gene.
4. Alleles are the alternative forms of a single gene.
5. A gene is a DNA segment that codes for a specific trait.

Answer:

• DNA located in the nucleus of a cell. → Nuclear DNA
• a cell containing all the DNA except the sex of a human; body cells. → Somatic Cells (body)
• portion of gene that is expressed. → exon
• an alternative form of a gene. → allele
• segment of DNA that codes for a trait. → gene
