The following points highlight the three main processes involved in the genetic recombination of bacteria. The processes are: 1. Conjugation 2. Transformation 3. Transduction. Process # 1. Conjugation: In this process, the exchange of genetic material takes place through a conjugation tube between the two cells of bacteria. The process was first postulated by Joshua Lederberg and Edward Tatum (1946) [...]
This article will guide you about how to study bacteria. Bacteria are minute organisms of enormous number with a high rate of multiplication. The smallest known bacterium is a little over 1 μm in size. Extreme precaution should be taken while handling bacteria—particularly pathogens (disease causing). Maintenance of an aseptic condition is a must in bacteria studies. I. Hanging drop [...]
The upcoming discussion will update you about the difference between Pili and Fimbriae. Difference # Pili: 1. They occur only in Gram negative bacteria. 2. The number is 1 -4 per cell. 3. Pili are longer and broader. 4. They help in conjugation. 5. Formation of pili is controlled by F+ or fertility factor. 6. They are tubular structures. Difference [...]
