What is a single loop of DNA found in bacteria?
bacterial plasmid/ plasmid ring
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.
Compare the transformation of a bacterium cell with the transformation of a plant cell?
In bacteria, if the plasmid containing the foreign DNA manages to get inside a bacterial cell, this sequence ensures that it will be replicated. In Plant Cells, if transformation is successful the recombinant DNA is integrated into one of the chromosomes of the cell.
How does the storage of the DNA of a prokaryotic cell differ from that of a eukaryotic cell?
In a eukaryotic cell DNA is stored in a nucleus as chromatin ( unless the cell is in the process of mitosis in which the DNA would arrange itself as chromosomes) However a prokaryotic cell has no nucleus, the genetic material is stored in the cytoplasm of the cell, prokaryotic cells also have a plasmid which is a ring of DNA which is separate to the main genetic material. This plasmid contains DNA not found in the main genetic material. The plasmid is also in the cytoplasm.
What types of vectors are used to carry DNA from one species into the DNA of another species?
There is a structure called a plasmid which can do this; it is bacterial in origin.
What is an extrachromosomal piece of bacterial DNA that contains genes not essential for cell growth?
A Plasmid
Identify the component of the bacterial cell that is a ring-shaped piece of DNA that is NOT part of the main chromosome and often plays a role in antibiotic resistance?
That ring-shaped piece of DNA is called a plasmid. The plasmid is DNA nonetheless, and has the same components that a DNA normally has.

Explain how DNA technology transfer bacterial genes from cell to cell?
I think you must rethink about your question, but still I am giving the answer as I can understand that you are asking about recombinant DNA technology where bacterial DNA is used as it is a cloning vector (plasmid). In recombinant DNA technology the particular sequence of DNA that we want to replicate or want to produce in huge number, is attached either with plasmid of bacteria or a DNA of bacteriophage and thus produce the recombinant or hybrid DNA which is copied each time when the bacteria or bacteriophage multiply. In this way the hybrid DNA will be transferred from parent cell to daughter cells.
How is plasmid DNA inserted into the cell where the DNA originally come from?
by transformation
Compare the transformation of a bacterium cell with the transformation of a plant cell?

What is the most logical sequence of steps for splicing foreign DNA into a plasmid and inserting the plasmis into a bacterium?
I. Transform bacteria with recombinant DNA molecule II. Cut the plasmid DNA using restriction enzymes III. Extract plasmid DNA from bacterial cells IV. Hydrogen-bond the plasmid DNA to nonplasmid DNA fragments V. Use ligase to seal plasmid DNA to nonplasmid DNA
Where is plasmid DNA present in a cell?
it is present in the cytoplam
A small ring of DNA that can be taken up by bacteria?
DNA is spliced into bacterial DNA in rings called plasmids.
Summarize three mechanisms of genetic recombination in prokaryotes?
The three ways in which genetic recombination occur in bacteria are:Tranformation - bacteria are able to take up foreign DNA through their cell membranes. This foreign DNA most often remains as an extrachromosomal structure called the plasmid. Sometimes the foreign DNA can integrate into the bacterial genome.Transduction - The transfer of small segments of bacterial DNA by viruses. When viruses invade the bacterial cell, they make use of the bacterial protein machinery to produce virions. During a process called packaging where genetic material is packed into the newly formed virus, bits of bacterial DNA are also included. These new virions then carry the bacterial DNA into the next cell that they infect.Conjugation - Also termed sexual reproduction between bacteria containing an F plasmid (F+) and one that lacks the plasmid (F-). A temporary structure called the conjugation tube is formed between the two interacting bacteria and the exchange of genetic material takes place.
