Plasmid A plasmid is a ring-shaped piece of DNA that is found within bacterial cells. Plasmids replicate independently of the chromosomal DNA found in the nucleoid but are always copied into next generation cells. Plasmids often contain genes that give bacteria genetic advantages such as antibiotic ...
(The DNA fragments are released into the environment by other bacteria.) To undergo transformation, a bacterium must be in a state known as competence. This usually happens when nutrients are scarce or when the density of a bacterial colony is high. In these circumstances, it might be ...

Metabolism is the sum of all chemical reactions in the body, Typically these concern the chemical reactions involved in the production of energy. Metabolism has three primary functions. These functions are to produce energy from food, convert energy into building blocks of the body such a...
Sex pili helps in bacterial DNA transfer during bacterial conjugation 3. Capsule It is a viscous outermost layer surrounding the cell wall. It is composed of either polysaccharides or polypeptides of both (~2%) and water (~98%). They are present only in some species of bacteria. The capsule...
While the infection itself is not considered dangerous, bacterial vaginosis should be treated with antibiotics. If not treated, the bacteria may spread up into the uterus or Fallopian tubes and lead to a more serious infection.Metronidazole(Flagyl) andclindamycin(Cleocin) are examples of antibiotics ...
How does RNA differ from DNA? What are some similarities between transcription and DNA replication? How is bacterial DNA replication different from eukaryotic DNA replication? Why do all cells have the same DNA but different functions? If all cells contain the same DNA, how do cells di...
