Science / Biology / Elongation: During protein synthesis, the growth of the polypeptide chain through the addition of amino acids; the second step in translation.

Region Of Elongation

Science / Biology / Region Of Elongation: The area in the tip of a plant root where cells grow by elongating, thereby increasing the length of the root. MORE

Zone Of Elongation

Science / Biology / Zone Of Elongation: Area in plant roots where recently produced cells grow and elongate prior to differentiation. MORE

Elastic Limit

Science / Geology / Elastic Limit: The maximum stress that can be applied to a body without resulting in permanent deformation - the rock reverts to its original shape after the stress is removed. In the case of a fault or a fold the e MORE


Science / Geology / Foliation: The planar or layered characteristics of metamorphic rocks that are evidence of the pressures and/or temperatures to which the rock was exposed. These can be structural such as cleavage, textural such MORE

Polymerase Chain Reaction (PCR)

Science / Biology / Polymerase Chain Reaction (PCR): A method of amplifying or copying DNA fragments that is faster than cloning. The fragments are combined with DNA polymerase, nucleotides, and other components to form a mixture in which the DNA is cyc MORE


Science / Biology / Translation: The synthesis of protein on a template of messenger RNA; consists of three steps: initiation, elongation, and termination. Making of a polypeptide sequence by translating the genetic code of an mRNA m MORE
