Is reverse transcriptase a virus or bacteria?
Reverse transcriptase is an enzyme found in retroviruses, which are a type of virus. It plays a key role in converting the virus's RNA genome into DNA for integration into the host cell's genome.
What is the function of the enzyme dicer?
Dicer is an enzyme that plays a key role in RNA interference (RNAi) and microRNA (miRNA) pathways. Its main function is to cleave double-stranded RNA into short RNA fragments, which are then used to regulate gene expression by targeting specific mRNAs for degradation.
What is the process making RNA to DNA?
The process of converting RNA to DNA is called reverse transcription. This process is carried out by the enzyme reverse transcriptase, which uses an RNA template to synthesize a complementary DNA strand. Reverse transcription is a key step in the replication of retroviruses like HIV and in the production of complementary DNA (cDNA) from RNA for use in research applications.
What finding changed the central dogma of molecular biology?
The discovery of reverse transcriptase was a key finding that changed the central dogma of molecular biology. This enzyme allows RNA to be transcribed into DNA, reversing the flow of genetic information in some viruses. This challenged the traditional concept that genetic information flows only from DNA to RNA to protein.
What is the key words of transcription?
The key steps of transcription are initiation, elongation, and termination. During initiation, RNA polymerase binds to the promoter region of DNA. Then, during elongation, the RNA polymerase synthesizes an RNA copy of the DNA template. Finally, termination signals the end of transcription and release of the RNA transcript.
What enzyme manufactures DNA that is complementary to a virus's RNA?
The enzyme that manufactures DNA complementary to the virus's RNA is called reverse transcriptase. Reverse transcriptase converts the viral RNA into DNA, which can then be integrated into the host cell's genome. This process is a key step in the replication cycle of retroviruses like HIV.

What is the importance of RNA Polymerase?
RNA polymerase is essential for gene transcription, as it catalyzes the synthesis of RNA using a DNA template. It plays a key role in gene expression and regulation by transcribing DNA into RNA, which is then translated into proteins. Without RNA polymerase, cells would not be able to produce the necessary proteins for their survival and function.
What effect does the lock and key process have on the enzyme structure?
Easily Explained thusly: When the key is in the lock the Enzyme has one Structure, and when the key is not in the lock the Enzyme has another Structure. Note that the presence of a key may either activate or deactivate an Enzyme, depending upon the conditions.

What sugar is found in RNA?
Ribose sugar is found in RNA. It is a five-carbon sugar that is a key component of the backbone of RNA molecules.
What is the key enzyme in nitrogen fixation?
The key enzyme in nitrogen fixation is nitrogenase. This enzyme is responsible for converting atmospheric nitrogen (N2) into ammonia (NH3), which can be used by plants and other organisms for growth and metabolism.
In the lock and key method which is the lock?
The Key is the substrate while the key is the enzyme. Just finished learning this :)
Why are virus's protein important?
They form the capsid that encloses the genetic material and retroviruses contain the protein enzyme reverse transcriptase. Also the proteins, especial glycoproteins, are the key that enters the lock of a cells protein markers.

What are the key components and processes depicted in an enzyme reaction diagram?
An enzyme reaction diagram typically shows the key components of an enzyme-catalyzed reaction, including the substrate, enzyme, active site, and products. The diagram also illustrates the process of substrate binding to the enzyme's active site, the formation of the enzyme-substrate complex, the catalytic reaction, and the release of the products.
