Question

Quizplus · Accepted Answer

A probe is a small single strand DNA molecule with a fluorescent molecule attached that is used to identify a clone containing a specific gene fragment. Primers are short DNA sequences used to initiate DNA synthesis during PCR. Plasmids are small, circular DNA molecules that replicate independently within a bacterial cell. Promoters are DNA sequences that control the initiation of transcription. Peptides are short chains of amino acids.
