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...

What are plasmid genes?
A plasmid is an extra chromosomal DNA molecule separate from the chromosomal DNA which is capable of replicating independently from the chromosomal DNA http://en.wikipedia.org/wiki/Plasmid I think this is far use.
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.
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 process in bacteria always allow both chromosomal and non-chromosomal DNA to be transferred?
Conjugation is a bacterial process that allows both chromosomal and non-chromosomal DNA to be transferred between cells. During conjugation, genetic material is exchanged through direct cell-to-cell contact facilitated by a structure called a pilus. This transfer of DNA can contribute to genetic diversity and adaptation within bacterial populations.
Which episome is carrying chromosomal fragment?
An episome carrying a chromosomal fragment is known as a F-prime (F') plasmid. It contains part of the bacterial chromosome along with the F plasmid DNA. The chromosomal fragment can be transferred between bacteria during conjugation.
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.

what are some exceptions to the cell theory?
Presence of extra-chromosomal DNA: Mitochondria and chloroplasts
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.
What organelles are found only in bacteria?
Some organelles found only in bacteria include plasmids (extra-chromosomal DNA), carboxysomes (protein-coated organelles for CO2 fixation), and magnetosomes (membrane-bound organelles for orientation sensing).
What is a synonym for plasmid?
A plasmid is essentially extra-chromosomal self-replicating DNA
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.

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.
