Which best describes transduction in bacteria?
Bacteria transfer DNA with a bacteriophage.
How can a bacterium produce restriction enzymes that do not cleave its DNA?
In order to protect the bacterial genomic DNA from its own restriction enzymes, bacterial cells employ a system, wherein methyl transferases methylate certain bases on the DNA sequence, making them unrecognizable to the restriction enzymes.Each restriction enzyme has a methylase associated with it on the chromosome. This methylase puts methyl groups on the host DNA, and the restriction enzyme doesn't recognize its recognition sequence when it is so methlyated. The host DNA is thus protected from the actions of its own restriction enzyme.Incoming (foreign) DNA is unlikely to be protected (methylated) in the same manner, thus this invading DNA is digested by the hosts restriction enzyme(s).When working in cloning experiments, the principle is the same -- DNA to be digested is carried by a plasmid in a host that does not methylate DNA in the pattern that would cause the restriction enzyme to see it as protected, thus it is cut. DNA generated by PCR is similarly unmethylated, and is therefore also digested.Some enzymes won't cut DNA isolated from dam+ or dcm+ hosts (two common bacterial methylases), thus one must know the genotype of the host cloning strain if using a restriction enzyme whose action is blocked by dam ordcmmethylation.
How much DNA do humans share with bacteria?
Humans share about 1-2 of their DNA with bacteria.
Why do bacteria, as prokaryotes, lack DNA?
Bacteria, as prokaryotes, do not lack DNA. In fact, they have DNA, but their genetic material is not enclosed within a nucleus like in eukaryotic cells. Instead, the DNA in bacteria is found in the cytoplasm in a region called the nucleoid.
Which is not a reason that scientists use bacteria DNA rather than human DNA in biotechnology?
Bacterial DNA is more interesting

Will bacteria cells have DNA?
Yes. Bacteria are living organisms. All living organisms have DNA.

Humans share about 1-2 of their DNA with bacteria.
DNA extraction from bacteria?
DNA extraction from bacteria can be achieved in various ways. Yeast is the best resource to extract the DNA bacteria from using extreme rapid extraction method.
Is DNA of bacteria any different from the DNA of the human?
No.

Is DNA found in bacteria?
Yes DNA or more specifically genetic material is one of the fundamental requirements for something to be classified as alive, which bacteria are. Bacteria do not conventionally have a nucleus so their genetic material is stored in plasmids, rings of DNA.
How much does a gallon of sodium methylate 30 weigh?
The weight of a gallon of sodium methylate 30 can vary based on its density, which is typically around 1.07 kg/L. Therefore, a gallon of sodium methylate 30 would weigh approximately 8.94 pounds (4.06 kg).
