How does plasmid allow for antibiotic resistance?
A plasmid (conjugative plasmid) that has a resistance gene on it, can transfer itself to another bacterial cell (called conjugation) or assist in the transfer of a non-conjugative plasmid that has a resistance gene to another cell (called mobilization). Whichever way it happens, once the plasmid is transfered to the new cell, this cell too may show signs of resistance to the particular antibiotic. This is one of the ways of the speard of resistance amongst bacteria
How are prophages and bacterial plasmids similar?
Prophages and bacterial plasmids are both genetic elements found in bacteria. They can replicate independently from the bacterial chromosome and confer certain traits to the bacterial host, such as antibiotic resistance. Additionally, both prophages and plasmids can integrate into the bacterial chromosome and be vertically inherited during cell division.
Identify the component of the bacterial cell that is a ring-shaped piece of DNA that is NOT part of the main chromosome and often plays a role in antibiotic resistance?
The component of the bacterial cell that fits this description is a plasmid. Plasmids are small, circular DNA molecules that replicate independently of the main bacterial chromosome. They can carry genes for antibiotic resistance and other advantageous traits that can be passed between bacteria.
Why a few bacterial colonies growing within the zone of inhibition?
Bacterial colonies growing within the zone of inhibition may indicate resistance or tolerance to the antibiotic used. This could be due to genetic mutations in the bacteria that enable them to survive or the presence of other resistance mechanisms. It is important to investigate further to understand the mechanisms behind this phenomenon and to consider using alternative antibiotics if necessary.
Increased resistance in bacteria after repeated exposure to antibiotics is due to?
mutations that allow the bacteria to survive the antibiotic's effects, leading to the selection of resistant bacterial strains. These resistant strains can then replicate and spread, making subsequent infections harder to treat. Additionally, the overuse and misuse of antibiotics can contribute to the development of antibiotic resistance.
How can specialized transduction contribute to the transfer of antibiotic resistance genes in a bacterial population?
Specialized transduction involves the transfer of a specific set of bacterial genes by a temperate bacteriophage during its lysogenic cycle. If the bacteriophage integrates into the bacterial chromosome near antibiotic resistance genes, they can be co-transferred to other bacteria upon phage infection. This process can facilitate the spread of antibiotic resistance genes within a bacterial population.
What are 4 evidences for evoluton?
Fossils, dogs, bacterial antibiotic resistance, & genetic comparisons.
What practices contributes the most to bacterial resistance to standard antibiotics?
Taking only half of an antibiotic prescription to treat a bacterial infection. Study Island
Do you take antibiotics for mono?
NO! Mononucleosis is caused by a virus. Antibiotics have no effect on viruses and can increase bacterial antibiotic resistance when misused.
How is the presence of antibiotic resistance used as a marker in bacterial transformation?
Antibiotics will kill off all of the bacteria that have not mutated and formed a resistance to the drug. Those that have a resistance to the antibiotics will survive and multiply into many resistant bacterium. This continuously facilitates the production of new kinds of antibiotic resistant bacteria
Is streptomyccin actinobacteria helpful or harmful?
Streptomycin is an antibiotic produced by the actinobacteria Streptomyces griseus, and it is used to treat bacterial infections in humans and animals. It is considered helpful in fighting certain types of bacterial infections, but overuse can lead to antibiotic resistance and harmful side effects.
What one plate would you first inspect to conclude that the transformation occurred successfully Why?
If you transform bacteria with a plasmid containing a selection marker (such as an antibiotic resistance gene) and plate the transformed bacteria on a plate suited for selecting for plasmid-containing bacteria (such as a plate containing an antibiotic that only those bacteria with antibiotic resistance can survive), then simply inspecting whether colonies are present on the plate will suffice in determining whether the transformation succeeded. If no colonies are found, that means no bacteria got the antibiotic resistance gene on the plasmid and the transformation was unsuccessful. If some colonies are found, that means some bacteria contain the plamis containing the antibiotic resistance gene and those colonies can the transformation was successful.

What is the function of a plasmid in a bacterial cell?
A plasmid in a bacterial cell serves as a small, circular piece of DNA that can carry extra genes, providing the cell with additional functions such as antibiotic resistance or the ability to produce certain proteins.
What do you use to treat bacterial infections?
an antibiotic
Why is it a problem in medicine for anibiotic resistance?
Antibiotic resistance happens when taking antibiotics more that it is required, high frequent doses will cause bacterial antibiotic resistance because in this case bacteria will get use into certain drug and so become ineffective. Resistance also happen when the patient has frequent illness, which make him/her taking the antibiotic for a long period of time. At that point patient should go the physician to describe him/her another effective drug, in order to kill bacteria and stop the illness.
