Verified step by step guidance1
Understand the process of transcription: Transcription is the synthesis of RNA from a DNA template. It involves the enzyme RNA polymerase and occurs in specific regions of the cell.
Recall the structure of a eukaryotic cell: Eukaryotic cells have membrane-bound organelles, including the nucleus, mitochondria, Golgi apparatus, and cytoplasm. Each organelle has specific functions.
Identify the location of DNA in a eukaryotic cell: DNA is stored in the nucleus, which is the control center of the cell. Transcription requires access to DNA, so it must occur where DNA is located.
Eliminate incorrect options: The Golgi apparatus is involved in protein modification and transport, not transcription. Mitochondria are responsible for energy production, and the cytoplasm is where translation (not transcription) occurs.
Conclude that transcription primarily occurs in the nucleus of a eukaryotic cell, as this is where the DNA template is located and RNA synthesis begins.
