Termination is the final step in a reaction where the reactive species are consumed to produce stable products, effectively stopping the reaction. In contrast, propagation steps are where reactive species are generated and utilized to carry out the main chemical transformations in a reaction, allowing it to proceed. Termination ends the reaction, while propagation keeps it going.

What is the final step of transcription?
The final step of transcription is the termination of RNA synthesis, where the RNA polymerase enzyme reaches a specific termination sequence in the DNA template. This signals the end of the gene, prompting the RNA polymerase to detach from the DNA and release the newly synthesized RNA molecule. The RNA undergoes further processing, such as capping and polyadenylation, before it is ready for translation.
What is the termination step that forms a bromoalkane?
The termination step that forms a bromoalkane typically occurs in a free radical bromination reaction. In this step, a bromine radical reacts with an alkyl radical to form the final bromoalkane product. This reaction involves the coupling of the two radicals, resulting in the formation of a stable carbon-bromine bond and the release of energy. The overall process is initiated by the generation of bromine radicals, often through the homolytic cleavage of Br2 in the presence of heat or light.
What are the illustrations of the different methods of artificial plant propagation?
The illustrations of different methods of artificial plant propagation include cutting, layering, division, grafting, and tissue culture. Visual representations can provide a step-by-step guide on how to execute each method effectively, aiding beginners in understanding the process better. These illustrations are commonly found in gardening books, online resources, and instructional videos to help enthusiasts propagate plants successfully.
What does the term artificial propagation mean?
Propagation carried out by man and not naturally.
Which step in what procedure represents transcription?
Transcription is the process of synthesizing messenger RNA (mRNA) from DNA. It occurs in the nucleus of the cell and involves three main steps: initiation, elongation, and termination. The initiation step involves the binding of RNA polymerase to the promoter region of the DNA.
What are the 3 steps in the free radical substitution?
The three steps in free radical substitution are initiation, propagation, and termination. In initiation, a free radical is generated. In propagation, the free radical reacts with a molecule to form a new free radical. In termination, two free radicals react with each other to form a stable product, ending the chain reaction.

What is chain termination?
Chain termination is any chemical reaction leading to the destruction of a reactive intermediate in a chain propagation step in the course of a polymerization, effectively bringing it to a halt.
What are the three steps to a chain reaction?
The three steps to a chain reaction are initiation, propagation, and termination. Initiation involves the initial trigger or activation of the reaction. Propagation is the process by which the reaction continues to spread through the system. Termination signifies the end of the reaction as the reactants are consumed or conditions change.
What are the steps to a chain reaction?
A chain reaction typically involves three steps: initiation, propagation, and termination. During initiation, the reaction is triggered by an initial event. In propagation, products from the initial reaction continue to react, creating more products. Termination occurs when the reaction eventually stops due to the depletion of reactants or other factors.
How many basic steps are involved in combustion?
Combustion typically involves three basic steps: initiation, propagation, and termination. In initiation, the fuel is heated to its ignition temperature. Propagation involves the sustained burning of the fuel as it reacts with oxygen. Termination occurs when either the fuel or oxygen supply is depleted, or when the combustion process is interrupted.
What is the final step in the natural process for making proteins?
The last step is reading the termination codon which will release the protein.
Can an employee sue for wrongful termination in Wyoming?
Labor Êand employment laws differ from one state to another. In Wyoming ,an employee can sue employer for wrongful termination, particularly for discrimination, breach of contract and retaliation for exercising you rights.Ê
What is the mechanism for radical substitution in CFCs?
In the mechanism of radical substitution in CFCs, a chlorine radical (Cl•) is generated by the homolytic cleavage of a C-Cl bond in the presence of ultraviolet (UV) light. This chlorine radical then attacks a C-H bond in a methane molecule, forming a new radical intermediate and releasing HCl. Finally, the new radical can continue the chain reaction by attacking another C-H bond, leading to the overall substitution of a chlorine atom for a hydrogen atom.
How does the propagation of sound as a longitudinal wave differ from other types of wave propagation?
Sound propagation as a longitudinal wave differs from other types of wave propagation in that it involves the compression and rarefaction of particles in the medium through which it travels, rather than the oscillation of particles perpendicular to the direction of wave travel. This unique movement of particles allows sound waves to travel through solids, liquids, and gases.
How does the motion of the medium differ between transverse and longitudinal waves?
In transverse waves, the particle motion is perpendicular to the direction of wave propagation, creating crests and troughs. In longitudinal waves, the particle motion is parallel to the direction of wave propagation, causing compressions and rarefactions in the medium.
How is termination spelled?
Termination
