Because the potatoes grow inside the hay bale, the bale can be positioned in areas where the soil is unsuitable for gardening or even on top of paved areas. However, water does drain from the bottom of the bale, so choose an area where this is not an issue.
Bacteria have exhibited colistin resistance in the past, but this time it is different: Previous forms of the resistance weakened the microbes, and the resistance genes were located on DNA that was not easily shared among bacteria.
Different species need different amounts of DNA. Therefore the copying of the DNA that precedes cell division differs between organisms. For example, the DNA in E. coli bacteria is made up of 4 million base pairs and the whole genome is thus one millimeter long.
