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.
Etymology: L, elongatio, a prolonging
a state of being lengthened or extended.
radiology Radiographic distortion in which the image appears longer than it is; caused by insufficient vertical angulation.
Stretching lengthwise or result of such action.
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.
one in a group of proteins involved in the elongation of polypeptide chains during protein synthesis.
