Transcription is the process where mRNA (Messenger RNA) is made.


Here are the steps of transcription.

1 ~ DNA is unzipped by the "Helicase" enzyme.

2 ~ RNA polymerase adds RNA nucleotides to the new RNA strand. (In RNA, thymine is replaced by uracil.)

3 ~ mRNA is complete when it reaches a stop code on DNA.

4 ~ mRNA then leaves the nucleus and carries the code to the sites of protein synthesis in the cytoplasm. (DNA never leaves the nucleus.)

Hope this helped :)
