Question

Quizplus · Accepted Answer

Polymerase chain reaction (PCR) is used to amplify DNA in the laboratory by making many copies of a specific segment of DNA. It is a technique that uses DNA polymerase enzyme, primers, and nucleotides to amplify a specific region of DNA. DNA cloning involves inserting a fragment of DNA into a vector for maintenance and replication. Reverse transcription is used to create a DNA copy of an RNA template. Nucleic acid hybridization is used to detect complementary DNA or RNA sequences. DNA restriction is used to cut DNA into smaller fragments at specific sites.
