Why do researchers us DNA polymerase from bacterium found in superheated water for PCR?
Ssass
because they are more durable in high temperatures. Increasing the temperature is a way to increase the enzyme's production rate. Normally, a protein will denature at high temperatures. This way you can have the best of both worlds.

Role of Taq polymerase in PCR?
taq polymerase is special because it is very stable at high temperatures and will not denature even at the 90 degree step of pcr. taq polymerase is so heat stable because it was extracted from the bacterium thermus aquaticus, which is found in hot springs and geezers
A ring of DNA found in a bacterium in addition to the bacterium's main chromosome is?
It's called a plasmid. The ring of DNA
What structures can be found in a bird's cell but not in a bacterium?
organelles
Design an enrichment medium to isolate detergent-degrading bacterium that is found in soil?
Begin with a bacterium containing soil. Then expose the soil to varying concentrations of detergents in an attempt to isolate the bacterium.
The type of bacterium most likely to be found in a swamp is?
methanogens

What is the role of e-coli bacterium?
e.coli is a bacterium found in the gut of animals which aids digestion, however it is commonly used for genetic engineering
What are the typical coliform found in water?
Coliforms represent normal bacterial flora found in the intestines of humans and animals.Examples of coliform found in water include:Enterotoxigenic E. coli (Gram negative bacterium) which causes traveler's diarrheaShigella spp. (Gram negative bacterium) which causes bacillary dysenteryVibrio cholerae (Gram negative bacterium) which causes choleraSalmonella enterica typhi (Gram negative bacterium) which causes typhoid fever
What are genetic materials found in a bacterium?
The genetic material in the bacterial cell is DNA.
A source of heat-stable DNA polymerase is?
A DNA polymerase is one of the crucial enzymes when DNA is synthesised. It is also the only enzyme needed when making DNA in the test tube, using a molecular biology technique known as PCR.In this reaction, the other enzymes that nature uses are are replaced by cycles of heating and cooling, up to 95 degrees Celsius. The DNA polymerase consists of protein, so normal DNA polymerase is of course destroyed in the heating step. The first PCR's were performed by opening the tube in each step and adding a tiny amount of fresh enzyme. Using heat-stable DNA polymerases made the technique a lot more practical. The enzymes used were taken från a type of archae (not exactly a bacterium, but almost) that live in hot springs and whose proteins all are very stable even in extreme temperatures. The archaeon is called "Thermus aquaticus", hence the name of the common lab DNA polymerases "Taq polymerase":To sum it up. A heat-stable DNA polymerase is a kind of DNA polymerase found in archaea living in hot springs, and of much use in the molecular biology lab.
Are promoters signals in RNA that indicate RNA polymerase when to begin transcription?
I found this information in my Biology textbook.
