In which part of a eukaryotic cell does transcription primarily take place?

• A. Nucleus
• B. Mitochondria
• C. Golgi apparatus
• D. Cytoplasm

Answer: (A)

Verified step by step guidance

1. Understand the process of transcription: Transcription is the synthesis of RNA from a DNA template. It involves the enzyme RNA polymerase and occurs in a specific location within the cell.
2. Recall the structure of a eukaryotic cell: Eukaryotic cells have membrane-bound organelles, including the nucleus, mitochondria, Golgi apparatus, and cytoplasm. Each organelle has distinct functions.
3. Identify the role of the nucleus: The nucleus houses the cell's DNA and is the site where transcription occurs. DNA is transcribed into messenger RNA (mRNA) within the nucleus before being transported to the cytoplasm for translation.
4. Eliminate incorrect options: The mitochondria are involved in energy production (cellular respiration), the Golgi apparatus is responsible for protein modification and sorting, and the cytoplasm is where translation occurs, not transcription.
5. Conclude that transcription primarily takes place in the nucleus of a eukaryotic cell, as it is the organelle containing the DNA template required for RNA synthesis.
