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.

chromosome

(ˈkrəʊməˌsəʊm)
n
(Genetics) any of the microscopic rod-shaped structures that appear in a cell nucleus during cell division, consisting of nucleoprotein arranged into units (genes) that are responsible for the transmission of hereditary characteristics. See also homologous chromosomes

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.

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.

nucleolar organiser, nucleolar organizer, nucleolus organiser, nucleolus organizer - the particular part of a chromosome that is associated with a nucleolus after nuclear division
chromatin, chromatin granule - the readily stainable substance of a cell nucleus consisting of DNA and RNA and various proteins; during mitotic division it condenses into chromosomes
cistron, gene, factor - (genetics) a segment of DNA that is involved in producing a polypeptide chain; it can include regions preceding and following the coding DNA as well as introns between the exons; it is considered a unit of heredity; "genes were formerly called factors"
sex chromosome - (genetics) a chromosome that determines the sex of an individual; "mammals normally have two sex chromosomes"
autosome, somatic chromosome - any chromosome that is not a sex chromosome; appear in pairs in body cells but as single chromosomes in spermatozoa
chromatid - one of two identical strands into which a chromosome splits during mitosis
centromere, kinetochore - a specialized condensed region of each chromosome that appears during mitosis where the chromatids are held together to form an X shape; "the centromere is difficult to sequence"
acentric chromosome - a chromosome lacking a centromere
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"
