| silver-fork deformity | The deformity resembling the curve of the back of a fork seen in Colles' fractures. (05 Mar 2000) |
| silver-fork fracture | A Colles' fracture of the wrist in which the deformity has the appearance of a fork in profile. (05 Mar 2000) |
| tuning fork | <instrument> A steel or magnesium-alloy instrument roughly resembling a two-pronged fork, the vibrations of the prongs of which, when struck, give a musical note of restricted band width; used to test the hearing and vibratory sensation. (05 Mar 2000) |

| fork | 1. An instrument consisting consisting of a handle with a shank terminating in two or more prongs or tines, which are usually of metal, parallel and slightly curved; used from piercing, holding, taking up, or pitching anything. 2. Anything furcate or like of a fork in shape, or furcate at the extremity; as, a tuning fork. 3. One of the parts into which anything is furcated or divided; a prong; a branch of a stream, a road, etc.; a barbed point, as of an arrow. "Let it fall . . . Though the fork invade The region of my heart." (Shak) "A thunderbolt with three forks." (Addison) 4. The place where a division or a union occurs; the angle or opening between two branches or limbs; as, the fork of a river, a tree, or a road. 5. The gibbet. Fork beam A mine is said to be in fork, or an engine to "have the water in fork," when all the water is drawn out of the mine. The forks of a river or a road, the branches into which it divides, or which come together to form it; the place where separation or union takes place. 6. To shoot into blades, as corn. "The corn beginneth to fork." Origin: AS. Forc, fr. L. Furca. Cf. Fourch, Furcate. (04 Apr 1998) |
| fork-tailed | <ornithology> Having the outer tail feathers longer than the median ones; swallow-tailed; said of many birds. Fork-tailed flycatcher, a graceful American kite (Elanoides forficatus). Synonym: swallow-tailed kite. Source: Websters Dictionary (01 Mar 1998) |
| bidirectional replication | A type of DNA replication where replication is moving along in both directions from the starting point. This creates two replication forks, moving in opposite directions. (09 Oct 1997) |
| virus replication | The process of intracellular viral multiplication, consisting of the synthesis of proteins, nucleic acids, and sometimes lipids, and their assembly into a new infectious particle. (12 Dec 1998) |
| repetition/replication | There are four plots in a repetition/replication, the early, mid and late seral treatment plots and a control plot. A repetition/replication is also called a "block." There should be at least three repetitions/ replications in a research study to obtain statistical reliability. (05 Dec 1998) |
| replication | 1. A turning back of a part so as to form a duplication. 2. <molecular biology> The process of duplicating or reproducing, as the replication of an exact copy of a polynucleotide strand of DNA or RNA. Origin: L. Replicatio = a fold backwards (14 May 1997) |
| replication, DNA | A wondrous complex process whereby the ( parent ) strands of DNA in the double helix are separated and each one is copied to produce a new ( daughter ) strand. This process is said to be semi-conservative since one of each parent strand is conserrved and remains intact after replication has taken place. (12 Dec 1998) |
| replication origin | A unique DNA sequence of a replicon at which DNA replication is initiated and proceeds bidirectionally or unidirectionally. It contains the sites where the first separation of the complementary strands occurs, a primer RNA is synthesised, and the switch from primer RNA to DNA synthesis takes place. (rieger et al., glossary of genetics: classical and molecular, 5th ed) (12 Dec 1998) |
| replication site | The in vivo site on DNA of DNA replication. (05 Mar 2000) |
| conservative replication | <molecular biology> Replication of DNA in such a way that the original parent strands of the DNA molecule end up back with each other. The entire preexisting double-stranded DNA molecule is conserved during each round of replication. Compare: semiconservative replication. (09 Oct 1997) |
