Polymerase chain reaction. Polymerase chain reaction, (PCR), a technique used to make numerous copies of a specific segment of DNA quickly and accurately.
Replication = DNA copied into another molecule of DNA. Replication machine uses DNA polymerases, nucleotides (individual DNA bases), and a host of other proteins and RNA to copy DNA in eukaryotic cells. DNA can only be copied in one direction - 5â² to 3â². Transcription = DNA copied into RNA.
