DNA Transcription: Process and Mechanism of DNA Transcription

WebTranscription is the process by which genetic information in DNA is copied into RNA. The process occurs in the nucleus and is critical for gene expression. The three main steps involved in transcription are initiation, elongation, and termination. During initiation, RNA polymerase binds to a specific region of DNA called the promoter.

WebEukaryotic transcription is a tightly regulated process that requires a variety of proteins to interact with each other and with the DNA strand. Although the process of transcription in eukaryotes involves a greater metabolic investment than in prokaryotes, it ensures that the cell transcribes precisely the pre-mRNAs that it needs for protein synthesis. WebUnderstanding: • Transcription is the synthesis of mRNA copied from the DNA base sequence by RNA polymerase. Transcription is the process by which an RNA sequence is produced from a DNA template. RNA polymerase separates the DNA strands and synthesises a complementary RNA copy from one of the DNA strands. When the DNA …
