Abstract

A chromosome is a linear DNA molecule, which carries the hereditary information, that is, the genes. A number of proteins pack the DNA string in several higher orders of folding. The morphology of chromosomes is characterized by length, arm ratio, appendages and banding pattern and is usually characteristic for a species.
