Describe how mRNA is produced in humans.

DNA helicase separates the strands by breaking the hydrogen bonds.One of the strands is used as a template to transcribe the mRNA.(Complementary) base pairing occurs with free RNA nucleotides.A→U, T→A, C→G, G→CThe RNA nucleotides are then joined together by RNA polymerase.This forms pre-mRNA which is spliced to remove the introns and form mRNA.
