elongation

 [e-long-ga´shun]
1. the act or process of increasing in length.
2. a radiographic distortion in which the image is longer than what is being x-rayed.

e·lon·ga·tion

(ē'lon-gā'shŭn),
1. The increase in the gauge length measured after fracture in tension within the gauge length, expressed in percentage of original gauge length.
2. The lengthening of a macromolecule, for example, in the synthesis of long-chain fatty acids or in the synthesis of a protein.

elongation

[i′longā′shən]
Etymology: L, elongatio, a prolonging
a state of being lengthened or extended.

e·lon·ga·tion

(ē-long-gāshŭn)
radiology Radiographic distortion in which the image appears longer than it is; caused by insufficient vertical angulation.

e·lon·ga·tion

(ē-lawng-gāshŭn)
Stretching lengthwise or result of such action.

elongation (ē´lônggā´shən),

n the process or condition of increasing in length before breaking; indicates ductility (e.g., of a metal).
elongation, percent,
n 1. the increase in length of a material after fracture in tension.
n 2. a mechanical test usually employed to measure ductility.

elongation

1. in protein synthesis, cyclic process of growth of a polypeptide chain from mRNA attached to ribosomes. Requires mRNA, ribosomes, activated aminoacyl-tRNA, elongation factor EF-Tu activated with GTP.
2. in fatty acids, a process of adding carbon from acetyl CoA to a lengthening acyl chain. Mechanism for achieving diversity of fatty acids in biological systems.

elongation factor
one in a group of proteins involved in the elongation of polypeptide chains during protein synthesis.
