The mRNA generated below was produced in the  <em><u>nucleus </u></em>of the cell.
Messenger RNA or mRNA is a type of RNA that is an essential component of protein synthesis or gene expression. It is synthesized using the template that is the nucleotide sequence of DNA.
- The synthesis of the mRNA s called transcription
- The nucleus is the location of the production of mRNA in eukaryotic cells from linear DNA strands.
- It requires nucleotide triphosphates as substrates
- catalyzed by the enzyme RNA polymerase II. 
Thus, the process of making mRNA from DNA is called transcription, and it occurs in the nucleus.
