Guida verificata passo dopo passo1
Recall the central dogma of molecular biology, which describes the flow of genetic information from DNA to RNA to protein.
Understand that transcription is the process where DNA is used as a template to synthesize messenger RNA (mRNA).
Identify the cellular compartment where DNA is located in a typical eukaryotic cell; DNA is housed within the nucleus.
Recognize that transcription occurs where the DNA template is accessible, which is inside the nucleus, not in organelles like lysosomes, Golgi apparatus, or on ribosomes.
Conclude that since transcription requires DNA as a template, it primarily takes place in the nucleus of eukaryotic cells.
