Differences between DNA polymerase and RNA polymerase?
A polymerase is an enzyme that catalyzes the conversion of free nucleotides into a single strand. DNA polymerase differs from RNA polymerase in two major respects: * Like all enzymes, DNA polymerase is substrate-specific. DNA polymerase cannot extend a single strand of DNA; it needs at least a short segment of double-stranded DNA at the outset. * As its name implies, DNA polymerase incorporates deoxyribonucleotides into the new strand. RNA polymerase incorporates ribonucleotides. These differences mean that DNA polymerase is active when new DNA strands are formed, as in DNA replication, and RNA polymerase is active when new RNA is formed, as in transcription. Before DNA replication can begin, the two strands must uncoil, so that each can form a template for free nucleotides to attach to. But DNA polymerase cannot get started with a single strand! In vivo(in the cell) RNA polymerase, which is active in the presence of single-stranded DNA, catalyzes the incorporation of a handful of nucleotides into a new strand. The short length of double-stranded nucleic acid that is produced enables DNA polymerase to swing into action. This still leaves a potential difficulty: the nucleotides incorporated in the presence of RNA polymerase are the wrong sort (ribonucleotides). They are subsequently replaced by DNA polymerase. In vitro (during PCR, the polymerase chain reaction) a primer, specially synthesized in a laboratory, attaches to a specific segment of single-stranded DNA, and the DNA polymerase takes over from there. The primer consists of a short length of single-stranded DNA that uniquely complements a specific DNA segment that is targeted for amplification, for example for forensic analysis.In practice, there are several different DNA polymerases and RNA polymerases in an organism.
What is the action or movement of an organism as a result of a stimulus?
running from the object
What is PCR?
Taq are important in PCR because they are heat resistant and are required for polymerase action. Hence we use Taq Polymerase enzyme in PCR. Specially and their main role is "Heat Sensitive Polymerase Enzyme".
How are the accuracy of DNA and RNA assured?
Most DNA Polymerases and RNA polymerases have what is known as "proof-reading activity". This is the ability of the enzymes to check what bases they have added during DNA replication (in the case of DNA Polymerase) or transcription (in the case of RNA Polymerase), and if an error is found, splice it out and replace it with the correct base. The mode of action depends on the enzyme in question - some use endonucleases, and some use exonucleases; some work 5'-3' while others work 3'-5'. Also note that I said MOST polymerases have proof-reading capabilities...there are a few which do not (or don't proof-read very well).
The presence of a repressor protein prevents the action of what enzyme?
RNA polymerase.
Multiple copies of DNA can be produced by?
cloning a DNA library. genetic amplification. the use of reverse transcriptase. the action of DNA polymerase
What is poison poisonous?
A substance that, when introduced into or absorbed by a living organism, causes death or injury, esp. one that kills by rapid action even in a small quantity. (Can come in Pills, Liquid, gas)
What president introduced affirmative action?
French Fries
What action can help keep an organism warm?

Which fact is most important in explaining why wrong base pairs are rarely incorporated into the double helix?
Nucleotide pairing affects the action of DNA polymerase.
Usually begins after the story and characters have been introduced?
The characters are introduced in the exposition. After the exposition, the rising action begins to unfold, leading to the climax. Following the climax, the falling action leads to the resolution.
What happens to the nitrogen in organism's body when the organism dies?
When an organism dies the nitrogen in its body it is released by action of decomposers. A desert is a biome that is very dry and little precipitation.
Which action influences the abiotic components of an organism's environment?
Water Pollution
What do you call change in the environment that causes an organism to take action?
stimulus
Who was the us president who introduced affirmative action?
lbj executive order 11246
