| relaxed plasmid | A plasmid that replicatesindependently of the main bacterial chromosome and is present in 10-500 copies per cell. (09 Oct 1997) |

| relaxin | <protein> Polypeptide hormone produced by corpus luteum and found in the blood of pregnant animals. Acts, as its name suggests, to cause muscle relaxation during parturition. Human relaxin has an A chain of 24 amino acids and a B chain of 29. Has structural similarity to insulin. (18 Nov 1997) |
| relaxing enzyme | <biochemistry> Any of several enzymes, such ashelicase, that unwind DNA prior to its replication. (09 Oct 1997) |
| relaxosome | <cell biology> Complex multi subunit structure forming at the plasmid origin of replication which nicks supercoiled DNA. Origin: Gr. Soma = body (18 Nov 1997) |
| relay | 1. A supply of anything arranged beforehand for affording relief from time to time, or at successive stages; provision for successive relief. Specifically: A supply of horses placced at stations to be in readiness to relieve others, so that a trveler may proceed without delay. A supply of hunting dogs or horses kept in readiness at certain places to relive the tired dogs or horses, and to continnue the pursuit of the game if it comes that way. A number of men who relieve others in carrying on some work. 2. <physics> In various forms of telegrapfhic apparatus, a megnet which receives the circuit current, and is caused by it to bring into into action the power of a local battery for performing the work of making the record; also, a similar device by which the current in one circuit is made to open or close another circuit in which a current is passing. <physics> Relay battery, the local battery which is brought into use by the action of the relay magnet, or relay. Origin: F. Relais (cf. OF. Relais relaxation, discontinuance, It. Rilascio release, relief, rilasso relay), fr. OF. Relaissier to abandon, release, fr. L. Relaxare. See Relax.
