EF-Tu (elongation factor thermo unstable) is a prokaryotic elongation factor responsible for catalyzing the binding of an aminoacyl-tRNA (aa-tRNA) to the ribosome. It is a G-protein , and facilitates the selection and binding of an aa-tRNA to the A-site of the ribosome.
Pollen tube elongation is an integral stage in the plant life cycle. The pollen tube acts as a conduit to transport the male gamete cells from the pollen grain —either from the stigma (in flowering plants ) to the ovules at the base of the pistil or directly through ovule tissue in some gymnosperms .

Elongation is the most rapid step in translation. [3] In bacteria , it proceeds at a rate of 15 to 20 amino acids added per second (about 45-60 nucleotides per second). [ citation needed ] In eukaryotes the rate is about two amino acids per second (about 6 nucleotides read per second).
This diagram shows various possible elongations (ε), each of which is the angular distance between a planet and the Sun from Earth's perspective. In astronomy, a planet's elongation is the angular separation between the Sun and the planet, with Earth as the reference point. [1] The greatest elongation is the maximum angular separation.
Elongation may refer to: Elongation (astronomy) Elongation (geometry) Elongation (plasma physics) Part of transcription of DNA into RNA of all types, including mRNA, tRNA, rRNA, etc. Part of translation (biology) of mRNA into proteins; Elongated organisms; Elongation (mechanics), linear deformation
EF-Ts and EF-Tu dimer forming the elongation factor complex full structure The protein Qβ-Replicase is a tetrameric protein, meaning it contains four subunits. These subunits are the two elongation factors, EF-Tu & EF-Ts, the ribosomal protein subunit S1, and the RNA dependent RNA polymerase β-subunit.
The diagrams presented show how fatty acids are synthesized in microorganisms and list the enzymes found in Escherichia coli. [2] These reactions are performed by fatty acid synthase II (FASII), which in general contain multiple enzymes that act as one complex. FASII is present in prokaryotes, plants, fungi, and parasites, as well as in ...
