Protein synthesis
Transcription
-
Transcription takes place in the nucleus, because the DNA can not leave the nucleus.
-
The process begins with RNA Polymerase binding to the DNA in the nucleus and unzip the genes that need to be copied. Then the RNA Polymerase matches the RNA nucleotide's to the DNA nucleotide's that has been unziped. Then the complete mRNA strand is released and leaves the nucleus to go to the cytoplasm. The DNA zips back up.
Translation
-
The purpose of translation is to read and or follow the directions carried on the mRNA to make polypeptide.
This all takes place in the ribosome's, not in the nucleus.
The process of translation will start with the mRNA, the mRNA attaches itself to small parts of the ribosomes. The ribosome will read the mRNA codons and it will go in a 5' 3' direction, but it will start with AUG. The tRNA will drop off some of the amino acids that had matched with the codons. Once it gets to the stop codon then the ribosome will release the full polypeptide chain.
