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.
This plasmid can be introduced into a bacterium by way of the process called transformation. Then, because bacteria divide rapidly, they can be used as factories to copy DNA fragments in large quantities. A plasmid is a small, circular, double-stranded DNA molecule that is distinct from a cell's chromosomal DNA.Plasmids naturally exist in bacterial cells, and they also occur in some eukaryotes.Often, the genes carried in plasmids provide bacteria with genetic advantages, such as antibiotic resistance. Plasmids have a wide range of lengths, from roughly one thousand DNA base pairs to hundreds of thousands of base pairs.his plasmid can be introduced into a bacterium by way of the process called transformation.
