PCR (polymerase chain reaction) is a method to analyze a short sequence of DNA (or RNA) even in samples containing only minute quantities of DNA or RNA. PCR is used to reproduce (amplify) selected sections of DNA or RNA. Previously, amplification of DNA involved cloning the segments of int...

disadvantages. One-step RT-PCR combines first-strand cDNA synthesis (RT) and subsequent PCR in a single reaction tube. However, two-step RT-PCR entails two separate reactions, beginning withfirst-strand cDNA synthesis, followed by amplification of a portion of the resulting ...
After the RT, 5′-adapter (with respect to the final PCR product) is then ligated to the 3′ end of the cDNA (step 5). The random nucleotides introduced in the 5′-adapters can reduce ligation bias. PCR amplification will be performed afterwards to produce double-stranded DNA with 6-bp...

Alternatively, design primers within 2 adjacent exons spanning a large intron (greater than 500 nucleotides in length) (Figure 1). Under normal qPCR cycling conditions, amplification of this large PCR product would not be favored. A DNase treatment of the RNA before using reverse transcriptase to...
The present invention provides a PCR amplification tube used for multi-steps reaction. In the PCR amplification tube, another reaction poor or reservoir is added or made in a lump. In a closed environment, the multi-steps reaction can be done in the same PCR amplification tube. The said PCR...
The present invention also provides a wash-free PCR amplification tube used for direct gene detection, which includes a reaction tube, the tube is made up of tube cap and tube body. The molecule signal is immobilized on the reaction tube used for PCR. There is a transparent window in the ...

PCR:Polymerase chain reaction (PCR) is used when a scientist needs to make multiple (millions to billions) of copies of a very specific area of DNA in a test tube.Answer and Explanation: The first step of PCR is the denaturation step. This occurs at around 96°C. It heats the DNA ...
