A chromosome is a DNA molecule with part or all of the genetic material (genome) of an organism. Prokaryotes usually have one single circular chromosome, whereas most eukaryotes are diploid, like humans. Chromosomes in eukaryotes are composed of chromatin fiber. Chromatin fiber is made of nucleosomes. A nucleosome is a histone octamer with part of a longer DNA strand attached to and wrapped around it.
A diploid has two sets of different DNA.. for example almost all human cells are diploid. There are 46 chromosomes in the human diploid cell. A haploid cell has half of the genetic information of diploid cells. A human haploid cell has 23 chromosomes. These cells are the sperm and the egg. Coming together, each of their 23 chromosomes combine to make a baby with 46 chromosomes.
