1. Accessory pigments
Light-absorbing pigments such as carotenoid s and phycobilin s that serve as complements to chlorophyll in plants, algae and bacteria by trapping light energy for photosynthesis .

2. Ambisense expression strategy
The coding of viral protein s in both the sense (coding) and antisense (noncoding) strands of complementary mRNA , so that the viral proteins are produced no matter which strand gets translated .

3. Amboceptor
An antibody which can combine both with a cellular antigen (such as a virus or bacterium ) and with a complement because it has two combining elements.

4. Anaphylatoxins
The C3a and C5a fractions during complement fixation. They act to mimic some of the reactions of anaphylaxis and can induce the release of histamine from mast cell s. C5a is also chemotactic for neutrophil s and monocyte s.

5. Anneal
* The sustained heating of a material such as steel or glass at a specific high temperature, followed by gradual cooling; this is done to eliminate weakness or to produce other qualities. * The pairing of complementary DNA or RNA sequence s, via hydrogen bonding , to form a double-stranded molecule. Most often used to describe the binding of a short primer or probe .

6. Antisense RNA (anti-sense RNA)
A complementary RNA sequence that binds to (and thus blocks the transcription of) a naturally-occuring (sense) messenger RNA molecule.

7. CDNA library (copy DNA library)
A library composed of complementary copies of cellular messenger RNA s.

8. Cis-trans test (complementation test)
A lab test which is used to determine whether two mutation s of different gene s which affect the same phenotype are on the same functional unit (indicating a cis configuration of the mutated genes) or on different functional units (indicating a trans configuration of the mutated genes). (A functional unit can be a chromosome .) The test is done by mating an individual that has one of the mutations to an individual that has the other one, and observing whether their offspring have the mutant phenotype. If the offspring do not have the mutant phenotype, then the genes are known to be trans, because the offspring have normal copies of each mutant gene on the different functional units which are able to genetically complement each other. If the offspring do have the mutant phenotype, then the genes are known to be cis, because the offspring will always inherit at least one of the mutant genes on the one functional unit, resulting in the mutant phenotype.

9. Complement
* A protein system that helps antibodies stage a defense against antigen s. * A biochemical substance (e.g. protein, vitamin , mineral, etc.) that is added to a food to improve its nutritional quality or to correct a deficiency created in cooking or processing.

10. Complement fixation
The consumption of complement by an antibody - antigen reaction.
