Where and why does transcription occur

This process is called translation. Where does transcription occur and where does translation occur in the cell? Apr 9, Transcription occurs in the nucleus, whereas translation occurs in the cytoplasm. Explanation: Terms transcription and translation in biology are generally related to the DNA and its properties. Related questions How can transcription be terminated?

Overview of Transcription. Triplets are groups of three successive nucleotide bases in DNA. Codons are complementary groups of bases in mRNA. Transcription takes place in three steps: initiation, elongation, and termination. The steps are illustrated in Figure 2. Figure 2. This page has been archived and is no longer updated. DNA safely and stably stores genetic material in the nuclei of cells as a reference, or template. Meanwhile, mRNA is comparable to a copy from a reference book because it carries the same information as DNA but is not used for long-term storage and can freely exit the nucleus.

Transcription is carried out by an enzyme called RNA polymerase and a number of accessory proteins called transcription factors. Nature Education 1 1 How would you make transcription and translation work when you no longer have a nucleus?
