Does bacteria have plasmids?

In: Microbiology, Genetics [Edit categories]

Answer:

Bacteria carry plasmids which is a double stranded DNA . It is how their extra chromosomal DNA is stored, they also have chromosomal DNA.

Plasmids are extra-chromosomal DNA in Bacterial cells that replicate independently in cell. Plasmids are ubiquitous- means significant number of bacteria have plasmid and can have more that one plasmids. But Plasmids do not occur in all bacterial isolates.

Relevant answers:

Plasmids are found only in bacteria?
Although several bacteria has plasmids, they have also been reported in certain varieties of plants and also in certain insect cells
What are bacteria plasmids made of?
Plasmids are essentially DNA, meaning they have the same components that make up the DNA, which includes phosphate, deoxyribose, and nitrogen bases.
Can plasmids be transferred into other bacteria?
Plasmids are often transferred to other bacterial cells via the sex pilus. This mechanism is a major cause in the spread of antibiotic resistance genes.
What a plasmid is and how does it confers resistance to bacteria?
a plasmid is an extrachromosomal circular DNA found in many bacteria. they are retained by the bacteria coz they have genes which confer resistance to antibiotics
How does Resistant Plasmid resist a bacteria to an antibiotic?
Yes, R plasmid carries the information for antibiotic resistance. Examle Carbenecillin-resistant gene, tetracycline-resistance gene, and chloramphenicol-resistance gene.
