| graph | 1. A line or tracing denoting varying values of commodities, temperatures, urinary output, etc.; more generally, any geometric or pictorial representation of measurements that might otherwise be expressed in tabular form. 2. Visual display of the relationship between two variables, in which the values of one are plotted on the horizontal axis, the values of the other on the vertical axis; three-dimensional graphs that show relationships between three variables can be depicted and comprehended visually in two dimensions. 3. <suffix> Something written, as in monograph, radiograph. The instrument for making a recording, as in kymograph, also, a writer; as autograph, crystograph, telegraph, photograph. Origin: Gr. Grafein, to write (20 Jun 2000) |

| vis | 1. Force; power. 2. Physical force. Moral power. <physiology> Principle of vis viva, living force; the force of a body moving against resistance, or doing work, in distinction from vis mortua, or dead force; the kinetic energy of a moving body; the capacity of a moving body to do work by reason of its being in motion. See Kinetic energy, in the Note under Energy. The term vis viva is not usually understood to include that part of the kinetic energy of the body which is due to the vibrations of its molecules.

| cis trans test | <molecular biology> The complementation test with two or more interacting genes placed in cis and in trans relationships to each other. A double mutant genome is used in the cis test made from the two single mutant genomes used in the trans test by recombination. If the wild type phenotype is restored by both cis and trans arrangements it is concluded that the two mutations are in different genes and hence that the phenotype is determined by more than one gene. If the trans test is negative and the cis positive this means that the two mutations are in the same gene. If both tests are negative then at least one of the mutations must be dominant. Thus the double test provides a means of fine mapping of genes. A lab test which is used to determine whether two mutations of different genes 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.

| trans- | 1. Prefix denoting across, through, beyond; opposite of cis-. 2. In genetics, denoting the location of two genes on opposite chromosomes of a homologous pair. 3. In organic chemistry, a form of geometric isomerism in which the atoms attached to two carbon atoms, joined by double bonds, are located on opposite sides of the molecule. 4. In biochemistry, a prefix to a group name in an enzyme name or a reaction denoting transfer of that group from one compound to another; e.g., transformylase (transfers a formyl group), transpeptidation.
