1. A linear strand of DNA and associated proteins in the nucleus of eukaryotic cells that carries the genes and functions in the transmission of hereditary information.
2. A circular strand of DNA in bacteria and archaea that contains the hereditary information necessary for cell life.

chro•mo•some

(ˈkroʊ məˌsoʊm)

n.
one of a set of threadlike structures, composed of DNA and a protein, that form in the nucleus when the cell begins to divide and that carry the genes which determine an individual's hereditary traits.
[< German Chromosom (1888); see chromo-, -some3]
chro`mo•so′mal, adj.

chro·mo·some

(krō′mə-sōm′)
A structure in all living cells that carries the genes that determine heredity. In all cells except bacterial cells, the chromosomes are thread-like strands of DNA and protein that are contained in the nucleus. They occur in pairs in all of the cells of eukaryotes except the reproductive cells. In bacterial cells, which have no nucleus, the chromosome is a circular strand of DNA located in the cytoplasm.

acrocentric chromosome - a chromosome with the centromere near one end so that one chromosomal arm is short and one is long
metacentric chromosome - a chromosome having two equal arms because the centromere is in median position
telocentric chromosome - a chromosome like a straight rod with the centromere in terminal position
telomere - either (free) end of a eukaryotic chromosome; "telomeres act as caps to keep the sticky ends of chromosomes from randomly clumping together"
body - an individual 3-dimensional object that has mass and that is distinguishable from other objects; "heavenly body"
