Transcription in Eukaryotic Cells

Transcription in Eukaryotic Cells

What is transcription? Transcription is the process that creates RNA inside a cell. It is used to develop proteins inside the cytoplasm of a cell although the actual transcription happens in the nucleus and mitochondria. Since transcription does not happen in the cytoplasm, translation has to occur right after transcription takes place.

What happens during Transcription? During transcription messenger RNA (what carries information from DNA to the organelles that synthesize proteins) is transcribed from the original strand of a gene. RNA polymerase separates the two strands of DNA and puts together the RNA nucleotide pairs with the DNA. The moment the DNA has been transcribed the two DNA strands coil back together as the RNA is pushed out from the polymerase. When it has finally realized that it is finished the polymerase transcribes a 'terminator sequence' and the transcription ends, the RNA is released, and the polymerase releases from the DNA.
