Do all microbes have plasmids?
No, not all microbes have plasmids. Plasmids are small, circular pieces of DNA that are separate from the microbial genome. While plasmids are common in many bacteria, they are not present in all microbes.
Why do bacteria have extra chromosomal DNA?
Extra chromosomal DNA - plasmids- are useful to bacteria as they possess favourable genes conferring resistance to certain toxins/antibiotics and/or assist with the survival of the bacteria through metabolic benefits. The extra chromosomal DNA is only maintained if it has a purpose so a plasmid conferring antibiotic resistance will not be maintained by a bacterium in an antibiotic free environment...
Do bacteria cell have single or multiple chromosomes of dna?
Bacteria cells typically have a single chromosome of DNA, which is circular in shape. This DNA molecule contains all the genetic information necessary for the bacterium to survive and reproduce. Some bacteria may also have plasmids, which are smaller, extra-chromosomal pieces of DNA that carry additional genetic information.
What is the difference between plasmid and episomes?
Plasmid DNA is an extra-chromosomal DNA molecule, it cannot link up with chromosomal DNA, and it contains the genetic informations that are necessary for its own replication. Episomes is any kind of extra-chromosomal DNA that can link up with chromosomal DNA. That is the main difference between them two. Episomes are usually larger than other extra-chromosomal DNA. An example of episome are the viruses, because they intergrate their genetic material into the host's chromosomal DNA.The only difference between the plasmid and the episome is the integration i-e plasmid can not integrate while episome can integrate into the genome.
Is human cell contain plasmid?
Plasmid is the property of prokaryotic cell i.e. of bacteria generally no mamalian cell have plasmid but ya there can be chances to have lillte part of DNA sequence to be simillar that of plasmid DNA sequence in prokaryotes
Small circular molecules of extra DNA in bacteria are called what?
plasmids
Bacteria often have small extra loops of DNA called?
Plasmids
What are Extra-chromosomal DNA particles capable of independent replication are called?
Extra-chromosomal DNA particles capable of independent replication are called plasmids. Plasmids are circular DNA molecules found in bacteria that can replicate independently of the chromosomal DNA. They often carry additional genes that can provide advantages to the bacteria, such as antibiotic resistance.
Do all microbes have plasmids?
No, not all microbes have plasmids. Plasmids are small, circular pieces of DNA that are separate from the microbial genome. While plasmids are common in many bacteria, they are not present in all microbes.
What is inside the bacterium below is a small circular piece of DNA called?
Inside the bacterium is a small circular piece of DNA called a plasmid. Plasmids can carry extra genes that provide advantages to the bacterium, such as antibiotic resistance. They can replicate independently from the bacterium's chromosomal DNA.
Can a bacteraial plasmid replicate independently of the bacterial chromosome?
Yes, bacterial plasmids can replicate independently of the bacterial chromosome. Plasmids contain their own origin of replication, allowing them to replicate autonomously within the bacterial cell. This characteristic is advantageous for manipulating plasmids in genetic engineering experiments.

Small DNA loops are called?
Small DNA loops are called plasmids. Plasmids are small, circular DNA molecules that are separate from the chromosomal DNA of a cell. They are often found in bacteria and can replicate independently.
What are the 2 types of DNA plasmids found in microorganisms?
Plasmids are autonomous DNA molecules of varying size which are localized within the cytoplasm of bacteria. There are two kinds:virulence plasmids = determines the virulence factors of the bacteriaresistance plasmids (R-plasmids) = determines the bacteria's resistance to anti-infective agents
What is the function of plasmid DNA?
Plasmids have small pockets of DNA in them.
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.
