What is the function of PCR in molecular biology?
The function of PCR in molecular biology is to amplify a specific segment of DNA, making multiple copies of it for further analysis and study.
What is the function of EDTA in DNA extraction processes?
EDTA is used in DNA extraction processes to chelate divalent cations, such as magnesium, which are necessary for the activity of DNases that can degrade DNA. By removing these cations, EDTA helps protect the DNA from degradation during the extraction process.
What are some common questions about PCR that researchers often encounter?
Some common questions that researchers often encounter about PCR include: How does PCR work? What are the different types of PCR techniques? What are the limitations of PCR? How can PCR results be validated? How can PCR be optimized for better results? What are the potential sources of error in PCR? How can PCR be used in different research applications? What are the ethical considerations when using PCR in research? How can PCR be used in clinical diagnostics? What are the current advancements in PCR technology?
Why cant DNA polymerase from organisms be used in pcr?
Many DNA polymerases from organisms are not suitable for PCR because they do not possess the optimal features required for the enzymatic reactions involved in PCR, such as high processivity, thermostability, and fidelity. PCR generally requires a DNA polymerase that can withstand the high temperatures used during the process without denaturing. Taq polymerase, isolated from the thermophilic bacterium Thermus aquaticus, is commonly used for PCR due to its ability to function at high temperatures.
What is the purpose of mgcl in pcr?
The enzyme DNA polymerase ( Taq polymerase) used in the PCR requires Mg 2+ ions for its functioning.These Ions act as cofactors for the enzyme . Hence the requirement for the use of Mg Cl2 in PCR reactions.

What effect does EDTA have when added to a lactase meditated reaction?
EDTA removes the ions that lactase needs to function as an enzyme. If enough EDTA is added, lactase will no longer have any of it's ion cofactors to aid in the break down of lactose.
What is the function of tris hcl in PCR buffer?
Tris HCl in PCR buffer helps to maintain a stable pH during the PCR reaction. It acts as a buffering agent, preventing pH changes that could affect the efficiency of the DNA amplification process. This helps to optimize the conditions for the PCR reaction to occur successfully.
What is the function of EDTA in DNA extraction processes?
EDTA is used in DNA extraction processes to chelate divalent cations, such as magnesium, which are necessary for the activity of DNases that can degrade DNA. By removing these cations, EDTA helps protect the DNA from degradation during the extraction process.
What are the different types of polymerase chain reaction techniques?
types of pcr: AFLP -PCR. Allele-specific PCR. Alu-PCR. Assembly -PCR. Assemetric -PCR. Colony -PCR. Helicase dependent amplification. Hot start pCR. Inverse -PCR. Insitu -pCR. ISSR-PCR. RT-PCR(REVERSE TARNSCRIPTASE). REAL TIME -PCR
What is the function of EDTA in the motility medium?
EDTA is known to be used in mixtures where metal ions are present. So to avoid these metal ions from binding to the other components, EDTA is added to bind them and thus chelation takes place. Metal ions are known to bind to the flagella of bacterial cells.
What is the function of hhsnna in edta titration?
In EDTA titration, hhsnna (hydroxylamine hydrochloride) is used to reduce any interfering metal ions present in the sample to prevent their titration by the EDTA solution. This helps ensure that the titration results are accurate and only reflect the concentration of the target metal ion being measured.
What the function of edta during protein extraction?
glycerol increases the stabilization of the protein by decreasing the surface tension of water

What is pcr and types of pcr?
PCR is a biotechnological method to amplify your gene (DNA) of your interest. It produce millions of your DNA fragments hence used in cloning. There are variants of this method using the same thermocycling principle such as touch down PCR, gradient PCR, RFLP, multiplex PCR, Q PCR, RT PCR and so on.
What is the function of tris and EDTA buffer?
Tris buffers provide a stable pH environment for biochemical reactions, while EDTA chelates metal ions to prevent enzymatic degradation. When used together, the Tris-EDTA (TE) buffer is commonly used for nucleic acid storage and as a buffer in molecular biology applications.
