What is genetic material? Genetic material is the hereditary substance in the cell. It carries all information specific to an organism. It is known as DNA (deoxyribonucleic acid) or RNA (ribonucleic acid). Where is genetic material found? The cytoplasm of prokaryotes such as bacteria contains DNA. In … See more Scientists studied the structure and function of the genetic material and found that the genetic material is located in the chromosomes. Because chromosomes contain proteins and DNA so it was not clear early on … See more The genetic material is extremely important since it keeps all information about the organism. The variety of genetic composition between individuals is a result of differences in the sequence and order of the bases forming … See more WebBiology is the study of life.

WebKey points: In transformation, a bacterium takes up a piece of DNA floating in its environment. In transduction, DNA is accidentally moved from one bacterium to another by a virus. In conjugation, DNA is transferred between bacteria through a tube between cells. Transposable elements are chunks of DNA that "jump" from one place to another.
