Bacteria Lab Write Up
Background
Bacteria have single circular chromosome that is not contained within the nucleus. They are haploid and reproduce by simple binary fission where one cell give rise to two new cells. There are several different ways of genetic recombination to occur in the bacteria, those are transduction, transformation and conjugation. Bacteria are autotrophic organisms which means that they can produce all needed nutrients using energy source and salts. They can be easily maintained and grown in the laboratory environment. Nevertheless, auxotroph bacterial strains which cannot grow on minimal media, ware used by Joshua Lederberg and Edward Tatum in 1946 to show that bacteria could transfer genetic material from one cell to another. They mixed
