WebSynchronized transcription elongation complexes (TECs) are a fundamental tool for investigating the biochemical properties of RNA polymerases (RNAPs) and nascent … WebTranscription takes place in three steps: initiation, elongation, and termination. The steps are illustrated in Figure 2. Step 1: Initiation. Initiation is the beginning of transcription. It occurs when the enzyme RNA polymerase binds to a region of a gene called the promoter.This signals the DNA to unwind so the enzyme can ‘‘read’’ the bases in one of …

"WebThe extent of the stretching/compression produced as the material responds to stress is called the strain (symbol \epsilon ϵ ). Strain is measured by the ratio of the difference in length \Delta L ΔL to original length L_0 L0 along the direction of the stress, i.e. \epsilon=\Delta L/L_0 ϵ = ΔL/L0.
