DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Transgenic carrots producing nisin protein show promise as natural food preservatives

Study explores the production of nisin protein in transgenic carrots, demonstrating its potential as a natural preservative effective against bacterial pathogens in food and juices.

Decoding the genome of world's biggest bacteria

Not all bacteria are created equal. Most are single-celled and tiny, a few ten-thousandths of a centimeter long. But bacteria of the Epulopiscium family are large enough to be seen with the naked eye and 1 million times the volume of their better-known cousins, E. coli.
