WebMar 16, 2015 · Typically, human somatic cells have 46 chromosomes; assuming that each chromosome is one long DNA-protein structure, it would have 46 DNA molecules that … WebA human sperm cell contains just one copy each of 23 chromosomes. A chromosome is made up of genetic material (one long piece of DNA) wrapped around structural support proteins (histones). Histones organize the DNA and keep it from getting tangled, much like thread wrapped around a spool. But they also add a lot of bulk.
