What is PCR? Polymerase chain reaction (PCR) is a common laboratory technique used to make many copies (millions or billions!) of a particular region of DNA. This DNA region can be …

PCR (Polymerase Chain Reaction) is a vital technique in molecular biology, enabling researchers to amplify specific DNA fragments exponentially. Essential for cloning, forensics, and medical …

Figure 1 Schematic of RT-PCR experiment. The position of the reverse transcriptase primer (Primer 1) and the positions of the PCR primers (Primers A and B) are shown. They then …

Since the DNA samples from vial 3 have three different lengths, does that mean three different target sequences were replicated when PCR was done and all three were later put into vial 3?

For your first question: You will do PCR of the entire sample. Then a restriction enzyme is used to cut the part you want. One restriction enzyme will make the cut on the same place in all …

Although genomes are now typically sequenced using other methods that are faster and less expensive, Sanger sequencing is still in wide use for the sequencing of individual pieces of …

Because of these possibilities, it's important to collect plasmid DNA from each colony and check to see if it matches the plasmid we were trying to build. Restriction digests, PCR, and DNA …

ATP structure, ATP hydrolysis to ADP, and reaction coupling.

DNA technology is important to both basic and applied (practical) biology. For instance, a technique used to make many copies of a DNA sequence, called polymerase chain reaction …

That’s because, during a ligation, DNA fragments don’t always get “pasted” in exactly the way we intend. Instead, we must collect DNA from several colonies and see whether each one contain …
