Plasmids are short sequences of DNA used as primers in PCR.

Question

Quizplus · Accepted Answer

Plasmids are small, circular pieces of DNA that can replicate independently of the chromosomal DNA. They are often used in genetic engineering as a way to clone genes, express proteins, or transfer genetic material between bacteria. However, they are not typically used as primers in PCR (polymerase chain reaction), which is a laboratory technique used to amplify specific DNA sequences. In PCR, primers are typically short pieces of single-stranded DNA that are complementary to the target DNA sequence and serve as starting points for DNA polymerase to replicate the target sequence.
