Here's a breakdown:
* DNA: The genetic blueprint of the cell is stored in DNA, located within the nucleus.
* Transcription: The process of copying the genetic information from DNA into mRNA.
* mRNA: Messenger RNA, a molecule that carries the genetic code from the nucleus to the ribosomes in the cytoplasm.
* Ribosomes: The sites of protein synthesis in the cell.
In summary: DNA resides in the nucleus, and the process of transcribing DNA into mRNA happens within the same compartment.
