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.
Summary. A chromosome is a single molecule of DNA, which represents a specific subset of information in the genome. A diploid organism has two copies of each chromosome, which are called homologous chromosomes or homologs.Chromatids refer to the copies of chromosomes produced during replication.ummary.
