Transcription takes place in the
A
cytoplasm
B
ribosome
C
mitochondrion
D
nucleus
Explanation: 

Detailed explanation-1: -During transcription, a piece of DNA that codes for a specific gene is copied into messenger RNA (mRNA) in the nucleus of the cell. The mRNA then carries the genetic information from the DNA to the cytoplasm, where translation occurs.

Detailed explanation-2: -The most prominent substructure within the nucleus is the nucleolus (see Figure 8.1), which is the site of rRNA transcription and processing, and of ribosome assembly.

Detailed explanation-3: -Thus, in eukaryotes, while transcription occurs in the nucleus, translation occurs in the cytoplasm.
