In most prokaryotes, the chromosome is usually a circular strand of DNA; hence, the entire genome is carried on only one chromosome.

WitrynaThere are 2n chromosomes in every somatic cell of many organisms , for humans 2n = 46, and in the germ line (sex cells) the chromosome number is n = 23, thus humans are diploid organisms (two copies of chromosomes).
