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 …

Learn about the polymerase chain reaction (PCR) technique, its applications, and how it amplifies DNA sequences in biotechnology.

Key points: Polymerase chain reaction, or PCR, is a technique to make many copies of a specific DNA region in vitro (in a test tube rather than an organism). PCR relies on a thermostable DNA …

Firstly, how would you select the sequence to do PCR with? Then, let's say you did gel electrophoresis and found out the DNA for the chosen sequence is 5000 bp long.

Learn about polymerase chain reaction (PCR), a technique used in molecular biology to amplify DNA sequences, on Khan Academy's comprehensive educational platform.

Key points: Polymerase chain reaction, or PCR, is a technique to make many copies of a specific DNA region in vitro (in a test tube rather than an organism). PCR relies on a thermostable DNA …

In this video, we are introduced to the world of molecular diagnostics. We particularly focus on one of the most common methods of molecular diagnosis - polymerase chain reaction or PCR - and how it can …
