Do cells take up more plasmids in some conditions and less in others?
Bacterial cells do not normally take up plasmids. However, scientists can use tricks to make them do so.
Bacterial cells which have been transformed with a plasmid are allowed to grow so that they the plasmids everytime they divide?
for plate answer is D
Do all microbes have plasmids?
No,all the microbes do not have a plasmid. Plasmids are present only in a bacterial cell.Plasmids are the extra chromosomal DNA which can replicate by itself.
Who discovered plasmodesmata?
Plasmids are found within the nucleus of a cell, it is a small, circular piece of DNA found in bacteria and yeasts, which is able to replicate independently of the chromosomes. They are predominantly found in prokaryotes (in the cytosol of prokaryotes and some eukaryotes.--*Though plasmids are found in eukaryotes such as yeast, they are very rare in eukaryotes in general. Plasmids are much more prevalent in prokaryotes such as bacteria. Bacterial plasmids may be linear or circular and are basically pieces of DNA that carry non-essential genes and replicate independently of the bacterial chromosome. Since bacteria don't have nuclei, bacterial plasmids exist freely in the cytosol in a supercoiled manner. Examples of bacterial chromosomes include the F plasmid, which is essential to bacterial conjugation (horizontal gene transfer) and various resistance plasmids that confer resistance to toxins including antibiotics.

Do fungal cells have plasmids?
It does not contain chloroplast because there is no any green pigment exist, and they doesn't make food by photosyntesis.
Can a bacteraial plasmid replicate independently of the bacterial chromosome?
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.
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.
Do all eukaryotic cells have plasmids?
Most plasmids are found in prokaryotic cells, but a few eukaryotic cells also have plasmids. An example of a eukaryote with plasmids is the unicellular yeast Saccharomyces cerevisiae.

What types of plasmids allows a bacterial cell to kill its competitors?
Bacteriocin Plasmids
Exogenous DNA can be inserted into bacterial cells in order to alter their genetic makeup and support expression of new protein products What are they?
Plasmids.
During transformation of bacterial cells chemicals that weaken bacterial membranes or pulses of electricity that temporarily tear tiny holes in the cells are used to do what?
Enable the faster and more numerous transfer of plasmids into the bacteria. (C for PLATO users.) ~Æ
What cell structure found in plant and bacterial cells but not animal cells called?
In Bacterial cells (prokaryotes) the genetic material is not enclosed in a nucleus, instead, it is a single strain of DNA in a circle with no end. Bacterial cells may also contain a few small strands of DNA, known as plasmids. Bacterial cells have a cell wall as well as a membrane. They also have cytoplasm as all cells do
In a bacterial cell, where would you find the DNA plasmids?
cytoplasm
Are plasmids found in plant or animal cells or both?
plasmids are found in plant cells only
