[DNA] [Distribution] and function

[DNA] [Distribution] and function


Prokaryotic cell chromosome is a long DNA molecule. Eukaryotic cells in more than one chromosome, chromosome each containing only a DNA molecule. But they generally than prokaryotic cells in the DNA and protein molecules and large combination. DNA molecules function is the storage of all species decision protein and RNA structure all the genetic information; orderly planning of biological cells and tissue components of time and space; identified throughout the life cycle of the biological activity and define the personality. In addition to chromosomal DNA, a very small amount of DNA found in different eukaryotic cells in the mitochondria and chloroplasts. DNA is the genetic material of the virus DNA.
