A small ring of DNA that can be taken up by bacteria?

A plasmid is a small ring of DNA that can be taken up by bacteria. Plasmids often contain genes that confer a selective advantage to the bacteria, such as antibiotic resistance. They can replicate independently of the bacterial chromosome.


In many bacteria genes that confer resistance to antibiotics are carried on what dissimilation plasmids exons plasmids factors or transposons?

Genes that confer resistance to antibiotics in bacteria are often carried on transposons. Transposons are mobile genetic elements that can move within a genome as well as between different genomes, allowing for the spread of antibiotic resistance genes among bacteria.


Explain why some plasmids contain a gene for resistance to an antibiotic?

Plasmids provide a mechanism for horizontal gene transfer within a population of microbes and typically provide a selective advantage under a given environmental state. Plasmids may carry genes that provide resistance to naturally occurring antibiotics in a competitive environmental niche, or the proteins produced may act as toxins under similar circumstances.


What are the properties of plasmid?

Plasmids are small, circular, extra-chromosomal DNA molecules found in bacteria. They often carry non-essential genes that can confer advantages such as antibiotic resistance. Plasmids can replicate independently of the bacterial chromosome, allowing for their easy manipulation and transfer between bacteria.


What type of plasmid is the source of the problem with antibiotic resistance?

The source of antibiotic resistance is often plasmids known as R plasmids, which carry genes that confer resistance to antibiotics. These plasmids can be transferred between bacteria, spreading antibiotic resistance throughout microbial populations.

What are the degradative plasmids and what are their properties?

Degradative plasmids are a type of plasmid that carry genes encoding enzymes which allow the host bacteria to degrade or metabolize specific compounds, such as pollutants or toxins. These plasmids can confer a selective advantage to bacteria in environments with those compounds, as they provide the ability to break them down for energy or survival. Examples include plasmids carrying genes for the degradation of hydrocarbons or pesticides.

What types of plasmids allows a bacterial cell to kill its competitors?

Plasmids can carry genes for producing toxins like bacteriocins or restriction enzymes that can inhibit or kill bacterial competitors, promoting the survival and proliferation of the host cell. These plasmids confer a competitive advantage to the host bacteria in environments where resources are limited.

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.


Can Candida albicans have plasmid?

Yes, Candida albicans can harbor plasmids, although they are not as common as in bacteria. Plasmids in C. albicans are often small and carry non-essential genes that can confer additional traits or function in specific conditions, such as drug resistance.


What is driver mutation?

The mutations that confer a selective growth advantage to the tumor cell are called “driver” mutations. It has been estimated. A driver gene is one that contains driver gene mutations. But driver genes may also contain passenger gene mutations A typical tumor contains two to eight of these "driver gene" mutations; the remaining mutations are passengers that confer no selective growth advantage.


What are cryptic plasmids and their properties?

Cryptic plasmids are plasmids that have no known function. They occur in a number of bacterial species. A plasmid is a circular loop of DNA, found, for the most part in prokaryotic cells (bacteria). It is much smaller than the single chromosome. Most bacterial plasmids fall into two main groups. There are relatively few copies per cell of large plasmids, with about 100,000 base pairs. These have enough genes to encode approximately 100 polypeptide chains. There are rather more copies of smaller plasmids that have around 10,000 or fewer base pairs (enough to code for up to about 10 genes). At least some cryptic plasmids have been found to contain replication genes.


Circular extra genomic DNA is called?

Circular extragenomic DNA is called a plasmid. Plasmids are commonly found in bacteria and carry additional genetic information that may confer advantageous traits, such as antibiotic resistance or pathogenicity. Plasmids can be transferred between bacterial cells through processes like conjugation, transformation, or transduction.
