What is transcription??
Transcription is the process where mRNA (Messenger RNA) is made.
These are the steps of transcription ~
1) DNA is unzipped by Helicase, which is an 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.)
