Answer:
Messenger RNA (mRNA) is synthesized during the process of transcription in the nucleus of a cell.
Step-by-step explanation:
When we talk about mRNA, we are referring to a molecule that carries genetic information from DNA to ribosomes, which are the protein-making factories of the cell. This mRNA molecule is synthesized during a process called transcription, which occurs in the nucleus of the cell. During transcription, an enzyme called RNA polymerase uses the DNA sequence of a gene as a template to create a complementary mRNA molecule. Once the mRNA molecule is synthesized, it is transported out of the nucleus and into the cytoplasm, where it can be read by ribosomes during the process of translation to produce a protein. Therefore, mRNA is synthesized during transcription, not translation.
