Rough endoplasmic reticulum
B
Nucleus
C
Golgi apparatus
D
Cytosol
Verified step by step guidance1
Recall that DNA transcription is the process where the genetic information in DNA is copied into messenger RNA (mRNA).
Understand that transcription requires access to DNA, which is located inside the nucleus in eukaryotic cells.
Recognize that the rough endoplasmic reticulum and Golgi apparatus are involved in protein synthesis and processing, but not in the transcription of DNA.
Note that the cytosol is the fluid outside the nucleus where translation (protein synthesis from mRNA) occurs, not transcription.
Therefore, conclude that DNA transcription primarily occurs in the nucleus, where the DNA is housed and RNA polymerase enzymes operate.
