What does hot start PCR do?|How can i speed my PCR?|

                           
                              HOT-Start PCR
Ø Hot start PCR is to use to minimize unwanted DNA product.
Ø Major disadvantages is PCR production of unwanted DNA amplification.
Ø Second step in addition to primer and tag polymerase. We add specific antibodies to back to polymerase from annealing.
Ø When temperature raises from amplification 7200c the specific antibodies detaches from tag polymerase and amplification being with great specificity.
Ø Modification of polymerase normally we add some antibody that will coat and being tag polymerase in normal room temperature is inactive them in room temperature antibody will properly function. So that tag polymerase can not initiate the polymerase chain reaction.
Ø As we start increase temperature at very first of the PCR reaction the temperature can 950c that is call HOT-start PCR.
Ø Because the HOT-start PCR higher temperature from beginning.
Ø Then that will inactive all antibody.
Ø Antibody will be degraded so that tag polymerase. Will free so that the elongate the primer properly.

Yeast two hybrid assay ?

Yeast two hybrid assay: -                                          Study interaction, detecting protein-protein interaction.   Principle of the two-hybrid: - A] Standard model of transcription activator: -     - The DNA binding domain of an activator binds to an enhancer.     - The activating domain interacted with the based complex. Recruiting it the promoter       B] Two hybrid assay for protein-protein interaction using gene clone technique linked the gene one protein to the part of a gene encoding a DNA binding domain, to encode 1 hybrid protein, linked the gene for another protein to the part of the gene encoding a transcription activating domain to encode a two hybrid proteins are introduce into yeast...

DMS footprinting?|DMS footprinting method?|how DMS footprinting works?

                                                   DMS footprinting -         Dimethyl sulphate (DMS) is one of the oldest and most versatile chemical reagents used to probe RNA structure. -         It was introduced for RNA structure mapping in 1980. This early method allowed detection of methylation by DMS at N 7 of guanosine and N 3 of cytidine nucleotide because of modification facilitate cleavage of the chain. -         The sites of the methylation were determined by polyacrylamide gel electrophoresis (PAGE) analysis of end-labelled RNA. -         Analogous method was used to footprint the binding of protein to DNA. -      ...

What is DNA helicase and its function?|How does helicase separate DNA?

                                                                    DNA helicase assay Ø Helicase is the enzyme that harness chemical energy of ATP to separate the two parental DNA strand at replicating fork is called a helicase. Ø Many DNA helicase have been identified in E . coli cells Ø The problem is in finding which of these is involved in DNA replication. 1.     Rep helicase 2.     DNA helicase II 3.     DNA helicase III Ø Without a functional helicase, the fork cannot more as DNA synthesis must had immediately. Ø The DnaB product was known to be an ATPase and the DnaB   protein was found associated with the primers which makes primers for DNA replicatio...
