Whereas the chromosomes of prokaryotes are relatively gene-dense, those of eukaryotes often contain regions of DNA that serve no obvious function. Simple single-celled eukaryotes have relatively small amounts of such DNA, whereas the genomes of complex multicellular organisms, including humans, contain an absolute majority of DNA without an identified function. This DNA has often been referred to as "junk DNA". However, more recent analyses suggest that, although protein-coding DNA makes up barely 2% of the human genome, about 80% of the bases in the genome may be expressed, so the term "junk DNA" may be a misnomer.

What type of organism has relatively gene dense chromosomes?
Answer: prokaryotes

The war ended on 26 October with Israel successfully repelling Egyptian and Syrian forces but having suffered over 2,500 soldiers killed in a war which collectively took 1035,000 lives in just 20 days.
