A __________ is a DNA molecule used in hybridization reactions to detect the presence of a particular gene in separated DNA fragments.

Question

Quizplus · Accepted Answer

A probe is a short strand of single-stranded DNA or RNA that has a base sequence that is complementary to a target DNA sequence. It is used to detect the presence of a particular gene or DNA sequence in separated DNA fragments. Probes are labeled with a detectable marker, such as a fluorescent dye or a radioactive isotope, so that the location of the target sequence can be identified. Plasmids and vectors are types of DNA molecules used to clone DNA fragments, while a blot is a technique used to transfer and visualize DNA fragments on a membrane.
