Question

transcription occurs in which of the following?
o the membrane
o the mitochondria
o a ribosome
o the nucleus

Explanation:

Transcription is the process of copying a segment of DNA into RNA. In eukaryotic cells, DNA is located in the nucleus. So, transcription occurs in the nucleus. The membrane is a general structure and not the site for transcription. Mitochondria have their own DNA and can do some transcription but the main site in the cell (for nuclear DNA - which is most of the cell's genetic material) is the nucleus. Ribosomes are the sites of translation (protein synthesis from mRNA), not transcription.

Answer:

The nucleus
