Final answer:
In human somatic cells, DNA is organized into 46 chromosomes, arranged into 23 pairs, which makes these cells diploid.
Step-by-step explanation:
In human somatic cells (all cells except gametes), DNA is organized into structures called chromosomes. Human somatic cells typically contain 46 chromosomes, arranged in 23 pairs. Each pair consists of one chromosome from each parent, making somatic cells diploid (2n), meaning they have two sets of chromosomes. The human genome in somatic cells therefore is organized into 23 homologous pairs of chromosomes, where homologous means they are paired chromosomes that have the same genes at the same loci but may contain different alleles (different versions of the same gene).
