Transcription begins - Cell gets message that a protein needs to be made & a portion of DNA unwinds exposing the gene that needs to be copied.

Nucleotides move in to form an mRNA molecule (U pairs with A) BUT THIS IS DIFFERENT FROM REPLICATION BECAUSE: 1.The nucleotides are mRNA nucleotides (ribose, phosphate, AGCU) 2.The nucleotides only move in to ½ of the DNA molecule.

mRNA leaves the nucleus through the pores to enter the cytoplasm (Codon = 3 bases)

mRNA leaves the nucleus through the pores to enter the cytoplasm (Codon = 3 bases) and the DNA rezips.
