![]() capping, polyadenylation, and splicing) ensue. In eukaryotes, post-transcriptional events (e.g. Finally, hydrogen bonds of the RNA-DNA helix break in order to release the newly synthesized mRNA transcript. ![]() RNA sugar-phosphate backbone forms on the RNA strand. RNA polymerase adds RNA nucleotides as it traverses the DNA template. RNA polymerase, then, escapes the promoter. Abortive initiation causes the formation and the release of small RNA products. A transcription bubble forms, opening the DNA strand and exposing a segment that will be transcribed. During initiation, RNA polymerase binds to the promoter region of the DNA. The general steps are initiation, promoter escape, elongation, and termination. Transcription is a biological process wherein a segment of the DNA is copied to mRNA. After this, the mRNA transcript that carries a copy of the coding segment of the DNA is brought to the ribosomal site for translation. It goes through polyadenylation, capping, and splicing. In eukaryotes, the mRNA transcript goes through further processing. In the last phase, the hydrogen bonds of the RNA-DNA helix break. ![]() The RNA polymerase escapes the promoter to proceed to the elongation step where mRNA transcript is formed while traversing the noncoding strand of the DNA. ![]() A phase of abortive cycles of short mRNA transcripts are produced and released. A site in the transcription bubble binds to the RNA polymerase. This causes the part of the DNA to unwind and form a transcription bubble. In brief, the RNA polymerase together with certain transcription factors binds to the DNA promoter. The general steps of transcription are (1) initiation, (2) promoter escape, (3) elongation, and (4) termination. In eukaryotes, it takes place inside the nucleus. In prokaryotes, the process occurs in the cytoplasm. In biology, transcription is the process of transcribing or making a copy of the genetic information stored in a DNA strand into a complementary strand of RNA ( messenger RNA or mRNA) with the aid of RNA polymerases. ![]()
