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.




- Q: Explain How Protein Synthesis Can Be Controlled At A Transcriptional Level In Prokaryotes
In prokaryotes, genes that encode enzymes of a metabolic pathway are usually clustered together on the chromosome in a region called an operon. A typical operon consists of regulatory sequences, like promoter, operator, terminator, and structural genes....

- Q: Outline The Differences Between Prokaryotic Control Of Gene Expression With The Eukaryotic Model
In the prokaryotic model, the regulation of transcription is by the control of operons. However, in the eukaryotic model, it is via the control of transcription factors. In prokaryotes, transcription can occur simultaneously with translation as there...

- Q: Compare And Contrast Dna Replication And Transcription
Similarities: Both processes occur in the nucleus. Both processes also involve specific complementary base pairing. Both processes involving the unwinding of the double helix DNA. Both processes involve forming of hydrogen bonds between the original DNA...

- Q: Compare And Contrast Transcription And Translation
Transcription occurs in the nucleus but translation occurs in the cytoplasm and rough endoplasmic reticulum. The two processes use different components and enzymes, transcription uses transcription factors and RNA polymerase whereas translation uses ribosomes...

- Eukaryote Transcription Vs. Prokaryote Transcription
Different Types of Transcription? Eukaryotes and Prokaryotes are different in so many ways but also the same. I explained a lot of the same and different ways in the "Eukaryotic and Prokaryotic Cells" post. One thing I did not describe was the transcription...
