Скачать или смотреть Structure of RNA Polymerase in Prokaryotes | Prokaryotic Transcription Explained Step-by-Step.

In this video, we explore the structure of RNA polymerase in prokaryotes and understand how this essential enzyme drives prokaryotic transcription. The discussion covers the core enzyme and holoenzyme, detailed roles of α, β, β′, ω, and σ subunits, promoter recognition (–10 and –35 regions), enzyme channels, and the catalytic mechanism of RNA synthesis.

This step-by-step explanation makes it easier to understand how RNA polymerase initiates, elongates, and regulates transcription in organisms like E. coli. The content is exam-oriented and student-friendly, specially designed for UG, PG, NEET, CSIR-NET, GATE, and other competitive exams.
