Yes, all bacteria have plasmids. Plasmids are a small, circular,double-stranded DNAmolecule that naturally exist in all bacterial cells. Every bacterial cell has its own plasmid which is separated from chromosomal DNA. These plasmids have the ability to replicate independently and are transferred dur...
A review on the distribution of linear and circular chromosomes in bacteria, telomer structures, and replication mechanisms of different microorganisms. The structures of the genomes of Borrelia and Streptomycetes species are discussed in detail.Redenbach...
Antibiotic resistance take place when fungi and bacteria get the capacity to endure antibiotics meant to destroy them. This shows that bacteria are not killed hence go on multiplying.Answer and Explanation: Plasmids frequently have methods for converting the plasmid to a new bacteria. This implies ...
How do bacteria acquire the capacity for biochemical warfare? Bacterial genes can be transferred by mobile genetic elements, such as plasmids. The transfer of genes between different species is called horizontal gene ... IMJRV Aarle 被引量: 0发表: 2006年 Computational Analysis of Neighboring Genes...
Why are bacteria such a useful source of enzymes? Explain why a solution with numerous enzymes from yeast cells can be used when testing the activity of a single enzyme like sucrase? Why is cytochrome P450 a beautiful enzyme? Why is rubisco the most important enzyme? What purpose does it se...
When fighting certain bacterial infections, the nodes swell up with bacteria and the cells fighting the bacteria, to the point where you can actually feel them. Swollen lymph nodes are a good indication that you have an infection of some sort. How You Can Help Your Imm...
How do bacteria reproduce so quickly? Bacteria reproduce through a process calledbinary fission. During binary fission, the chromosome copies itself, forming two genetically identical copies. Then, the cell enlarges and divides into two new daughter cells. ... Some species of bacteria can double ...
The plant pathogen Agrobacterium tumefaciens transports T-DNA and effector proteins into host cells using the VirB system, a prototypical T4SS. Many bacteria and conjugative plasmids encode T4SSs closely related to the VirB system, which are classified as type IVA (T4ASS)4. Structural studies ...
What cells have a flagella? A flagellum is a whip-like structure that allows a cell to move. They are found in all three domains of the living world:bacteria, archaea, and eukaryota, also known as protists, plants, animals, and fungi. ...
carry plasmids d. kill the bacteria causing release of endotoxins e. kill human cells Is smallpox a DNA or RNA virus? How did viruses evolve? Imagine that a virulent (T_4) phage is inoculated with a Gram negative human bacterial pathogen. Explain whether the bacteriophage will have lytic ...
