The enzyme complex that forms at the start of transcription is the Rna polymerase-promoter complex.
<h3>What is transcription?</h3>
Transcription is a biological process during which the information on DNA is transcribed into genetic codes in RNA.
The process of transcription occurs in 3 stages, which are:
- Initiation
- Elongation
- Termination
During initiation, an enzyme known as RNA polymerase binds to a region on the DNA to be transcribed. This region is known as the promoter region.
Thus, the binding leads to the formation of RNA polymerase-promoter complex, otherwise known as the initiation complex.

Blood cells is not in the filtrate that the Bowmans capsule collects
The clotting mechanism, chemicals released from damaged tissues trigger the cascade of events that ultimately result in the formation of hemostasis.
Hemostasis is reached by a series of actions known as the coagulation pathway or clotting mechanism. The complex system enables quick healing and stops uncontrolled bleeding. Fibrin activation is the result of the convergence at a certain site of two routes, intrinsic and extrinsic, which start off independently. The end goal is to use a fibrin mesh to stabilise the platelet plug.
The coagulation pathway's job is to maintain hemostasis, which is the cessation of bleeding or haemorrhaging. Primary hemostasis is the formation of a plug of platelets at the injured region where exposed endothelial cells are present.
