We use words to express our general meaning; we employ certain technical terms in reference to a given subject. To make use of, implies passivity in the thing; as, to make use of a pen; and hence there is often a material difference between the two words when applied to persons. To speak of "making use of another" generally implies a degrading idea, as if we had used him as a tool; while employ has no such sense. A confidential friend is employed to negotiate; an inferior agent is made use of on an intrigue.

Usus, to use, OL. Oeti, oesus; of uncertain origin. Cf. Utility. Source: Websters Dictionary (01 Mar 1998) |

| polymorphism, single-stranded conformational | Variation occurring within a species in the conformation of denatured DNA fragments. These single-stranded DNA fragments are allowed to partially renature in a way that prevents the formation of double-stranded DNA. The fragments are run on polyacrylamide gels under various conditions to detect subtle changes in migration due to altered secondary structure. The resulting bands will align themselves if the fragments are the same, but will misalign if any point mutations are present. Sscps have been used in detecting mutations in various genes, such as oncogenes, tumour suppressor genes, and genes responsible for genetic diseases. (12 Dec 1998) |
