|+||(Science: cell biology) The self-replicating genetic structures of [[cell]]s containing the cellular [[dna]] that bears in its nucleotide Sequence the linear array of genes. |
|+||The dna of eukaryotes is subdivided into chromosomes, that consist of a number of chromosomes whose dna is associated with various [[protein]]s. The chromosomes become more tightly packed at [[mitosis]] and become aligned on the metaphase plate. Each chromosome has a characteristic length and banding pattern. |
|+||in prokaryotes, chromosomal dna is circular, and the entire genome is carried on one chromosome. |
|+||See: c banding, g banding. a threadlike body in the cell nucleus that carries the genes in a linear order.The structures found within a cell that contain the genetic information of an organism. this [[genetic]] information is dna or mrna, deoxyribonucleic acid and messenger ribonucleic acid respectively. |
