In summary:
DNA unwinds
- next it unzips
- RNA polymerase occurs resulting in the RNA strand
- this is transported to the cytoplasm where RNA binds to ribosome
- the ribosome contains the start codon (AUG)
- tRNA with anti- codon and amino acid attached binds with the mRNA strand
- a second tRNA attaches and this continues with the amino acids forming a chain
- the first tRNA is released and only two tRNA can be present at a time, bringing the anti- codons and amino acids
- a polypeptide chain is formed
- the "stop" codon is reached where the polypeptide chain is released into the cytoplasm
I hope this aids you, apologies if the reply is late and for myself, this was a troublesome area too but textbooks make sense after a few readings.
