1. Aardvark (Orycteropus afer)
A nocturnal, burrowing southern African mammal, Orycteropus afer, which is characterized by a long snout and tongue for eating ants and termites. The name "aardvark" is Afrikaans for "earth pig."

2. Aloe vera
A succulent, fibrous plant, of the family Liliaceae, with basal leaves, having toothed or fibrous margins. Native to southern Africa, it is a popular ornamental, and its juice is used alone or in preparations to soothe minor burns and skin irritations.

3. Denhardt's solution
A solution commonly used during probe hybridization s that involve filters (such as southern, Northern, or Western blot s). The solution contains ficoll, bovine serum albumin, polyvinylpyrrolidone (PVP), and a high concentration of nonspecific DNA so the probe won't hybridize nonspecifically.

4. DNA fingerprint
The unique pattern of DNA fragments identified by southern hybridization (using a probe that binds to a polymorphic region of DNA) or by polymerase chain reaction (using primer s flanking the polymorphic region).

5. Electroblotting
The use of an electric field to transfer protein s or nucleic acid s from the electrophoresis gel to the blotting membrane as a part of southern blotting , Northern blotting , or Western blotting .

6. Electrophoresis (ionophoresis)
A method of separating large molecules (such as DNA fragments or protein s) from a mixture of similar molecules. An electric current is passed through a medium containing the mixture, and each kind of molecule travels through the medium at a different rate, depending on its electrical charge and size. Separation is based on these differences. Agarose and acrylamide gels are the media commonly used for electrophoresis of proteins and nucleic acid s. Specific electrophoretic methods include Northern blot , southern blot , and Western blot .

7. Fingerprinting (peptide mapping, nucleotide mapping)
A general term for techniques used to identify unique protein s or nucleic acid s by breaking them up with enzyme s and looking at the resulting pattern of their amino acid or nucelotide base sequences. Fingerprinting is widely used in forensics to test blood, semen or other body tissues for genetic matching. See also southern blot .

8. Gondwana
Name applied to the ancient ( Paleozoic -early Mesozoic ) southern hemisphere supercontinent that rifted apart to form present-day Antarctica, India, Africa, Australia, and South America. The southern part of Pangaea .

9. Northern blot (Northern hybridization, Northern blotting)
A technique similar to southern blotting , though it is used for RNA . In this technique, RNA fragments are transferred from an agarose gel to a nitrocellulose filter, where the RNA is then hybridized to a radioactive probe .

10. Ordovician extinction
Paleozoic-aged mass extinction possibly related to glaciation in the southern-hemisphere supercontinent Gondwana.
