The below mentioned article provides a note on the process of transcription. Transcription is the process of copying genetic information from one strand of the DNA into RNA. In transcription, only a segment of DNA or only one out of the two stands is copied into RNA. Unlike replication, which once set in, the total length of DNA of organisms [...]
In this article we will discuss about the process of transcription in prokaryotes and eukaryotes. Transcription in Prokaryotes: DNA dependent RNA polymerase is the single enzyme that catalyses the transcription of all types of bacterial RNA. (i) Initiation: RNA polymerase binds to promoter and initiates transcription. It associates transiently with 'initiation factor' (σ) and uses nucleoside triphosphates as substrate, obeying [...]
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 known as the coding strand [...]
