Nuclear Pore

The mRNA goes through the Nuclear Pore. It can leave the nucleus because it is only single stranded, so there is enough room for it to leave.

FINAL FORM

There are two steps to protein synthesis. They are transcription and translation. In transcription, the RNA polymerase binds onto the DNA strand. It then separates it and makes an mRNA strand, which then leaves the nucleus out of the nuclear pore, and is now in the cytoplasm. Next is translation. An anti-codon comes into play after the mRNA strand is in a ribosome. It makes a peptide bond and then the peptide bonds all fold up and make a certain protein with a specific function.
