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.
Diploid cells are cells which contain 2 sets of chromosomes, which will later be divided into two sets of 23 chromosomes for each daughter cell. The total will come up to be 46 chromosomes. The other type of cell is a haploid. A haploid is a sex cell which contains 23 chromosomes.
