Today we finished the chapter on transcription.
We discussed the process in which RNA polymerase binds to the promoter in prokaryotes, generates de RNA transcript, and reaches the terminator to end transcription (Rho-independent termination and Rho-dependent termination).
We then discussed eukaryotic transcription. The promoter is more complex (it has an initiator box, a TATA box, and upstream elements), there are three different RNA polymerases that transcribe nuclear genes (mitochondrial and chloroplast genes use other polymerases), and there are proteins, called transcription factors (general and specific), that aid RNA polymerases in the transcription of genes. Some proteins may bind to enhancer regions, upstream from the promoter, to aid in the process.
