The DNA undergoes two simplified process I becoming a protein; transcription and translation. Transcription involves the production of a complimentary mRNA strand in the nucleus. The double stranded DNA unzips enzymatically, next DNA polymerase binds to the unzipped DNA and binds complementary nucleotides from the 3' end to the 5' end. This newly formed mRNA strand then moves out of the nucleus where it binds with a ribosome, here complimentary tRNA molecules bind to the mRNA strand thus forming a primary structure protein.
