Very short pieces of DNA used to find specific sequences of "letters" in a very long piece of DNA from a chromosome.

Labeled substances that have specific affinity for the transferred proteins, DNA or RNA. They can be radioactive, chromogenic, fluorogenic, or enzyme conjugates of antibodies. Lectins, protein A and complementary DNA’s or RNA’s are among the common probes used. See Tag and Label.

Particular nucleic acid (DNA or RNA) molecules which can be used to detect specific nucleic acid sequences that are complimentary to the probes. The probes are labelled in some way so that, when hybridised with the complimentary nucleic acid, the probe can be detected. Probes are often labelled with either radioactive isotopes or fluorescent chemicals.

"Probes are primarily questions that interviewers interpose to get a respondent to clarify a point, to explain further what she meant, to continue talking, or to shift the topic" (Zeisel, 1984, p.140).

Unmanned spacecraft which are launched into space in order to collect data about the solar system and beyond. Space probes are not necessarily designed to return to Earth. QUANTUM MECHANICS A theory in physics which is based on 2 ideas: (1) light can be emitted or absorbed only in discrete quantities called quanta, whose energy is proportional to their wavelength; and (2) you can never be exactly sure of the position and velocity of a particle, the more accurately you know the one, the less accurately you can know the other.
