Answer:
In the nucleus, mRNA is formed from free floating nucleotides in a process called transcription. This process requires the enzyme RNA polymerase II.
Explanation:
mRNA (or messenger RNA) is transcribed from a DNA template in the nucleus. This uses the enzyme RNA polyermase II, which copies the DNA sequence to the RNA sequence using nucleotides. The RNA polymerase binds at gene promoters, where it transcribes the RNA by reading the DNA sequence until it reaches the termination signal to stop transcribing.
After this, the RNA molecule moves to the cytoplasm where it can be translated into protein.
