The processes of transcription, RNA processing (in eukaryotes), and translation constitute the pathway that leads to the conversion of genetic information in the linear sequence of bases in genomic DNA into the linear amino acid sequences of functional proteins. Thus, DNA undergoes transcription to ...

transcription and translation occur simultaneously in the cytoplasm, allowing for a rapid cellular response to an environmental cue. (b) In eukaryotes, transcription is localized to the nucleus and translation is localized to the cytoplasm, separating these processes and necessitating RNA processing for ...
Transcription occurs before translation because the DNA sequence needs to be transcribed into RNA before it can be translated into a protein. Therefore, transcription is the initial step in gene expression, followed by translation. Rate this question: 43 0 3. Messenger RNA (mRNA) can be ...

Figure 3.14.The cellular location of transcription, RNA processing, and translation. DNA is located in the nucleus, and therefore transcription occurs in the nucleus. The precursor mRNA also undergoes RNA processing in the nucleus before departing the nucleus through a nuclear pore. In the cytosol,...

Transcription, the synthesis of RNA from DNA. Genetic information flows from DNA into protein, the substance that gives an organism its form. This flow of information occurs through the sequential processes of transcription (DNA to RNA) and translation (
▸RNA splicing = processing the RNA to remove regions that will not be included in the final protein; ▸Export = preparing the processed RNA to be moved into the cytosol and translated into protein; ▸Translation = building of a protein according to the sequence of the messenger RNA; ...
