The below mentioned article provides notes on RNA synthesis. RNA synthesis, also known as DNA transcription, essentially consists of making an RNA copy of a segment of DNA. In this process, a complementary single-stranded RNA molecule is synthesized using one of the two strands of a DNA segment as template. The strand so copied is […]
The below mentioned article provides a study note on the transcription in prokaryotes. In prokaryotic organisms, transcription occurs in three phases known as initiation, elongation and termination with the help of single RNA polymerase. RNA Polymerase: RNA is synthesized by a single RNA polymerase enzyme which contains multiple polypeptide subunits. In E. coli, the RNA […]
The below mentioned provides a short note on the transcription in eukaryotes. Transcription occurs in eukaryotes in a similar way to prokaryotes. However, initiation is more complex, termination does not involve stem-loop structures and transcription is carried out by three enzymes (RNA polymerases I, II, III), each of which transcribes a specific set of genes […]
