Transcription takes place in the nucleus of the cell. The nucleus is a membrane-bound organelle that contains the cell’s genetic material, DNA. During transcription, the DNA sequence of a gene is copied into a messenger RNA (mRNA) molecule by the enzyme RNA polymerase. This mRNA molecule then carries the genetic information from the nucleus to the ribosomes in the cytoplasm, where it is translated into a protein.
In summary, the nucleus is the organelle where transcription occurs, playing a crucial role in gene expression and protein synthesis.
