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 cell will have two sets of chromosomes, one set from each parent. â¦ A haploid cell is a cell with only one set of chromosomes. For example, humans are diploid organisms-our cells each have two copies of 23 different chromosomes for a total of 46. A haploid cell is a cell with only one set of chromosomes.
