Termination of elongation depends on eukaryotic release factors. Proteins from inner membrane stops the process of chain elongation. Cdc42 was assumed to encourage filopodia elongation and block actin depolymerization. This is caused by frictional abrasion of the load-bearing surfaces of the chain causing elongation. It inhibits cell division and cell elongation. Brassinosteroids control cell elongation and division, gravitropism, resistance to stress, and xylem differentiation. Protein synthesis occurs in three phases&colon; initiation, elongation, and termination. This protein also interacts with netrin-1, which is involved in axon elongation. Ganciclovir triphosphate serves as a poor substrate for chain elongation. In order to terminate elongation dephosphorylation must occur. There will also be marked acanthosis with elongation and thickening of the rete ridges. This serves as the substrate for the next cycle of elongation. The "PT center is responsible for producing protein bonds during protein elongation". It consists of three steps&colon; Initiation, elongation, and termination. It consists of four phases&colon; initiation, elongation, termination, and recycling.
