Verified step by step guidance1
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 organelle where DNA is housed in a eukaryotic cell; this is the nucleus, which contains the cell's genetic material.
Recognize that transcription occurs in the nucleus because it contains the DNA and the necessary enzymes, such as RNA polymerase, to carry out this process.
Note that other organelles like ribosomes are involved in translation (protein synthesis), mitochondria have their own DNA but are not the primary site of transcription for nuclear genes, and the Golgi apparatus is involved in protein modification and sorting, not transcription.
