How are proteins synthesised?

Proteins are coded for by genes (a sequence of DNA that codes for a specific polypeptide), in the nucleus the DNA is unwound by an enzyme and then another enzyme with copy the template strand to make a molecule of mRNA, this will leave the nucleus via a nuclear pore and be delivered to a ribosome. Once it attaches to the ribosome molecules of charged tRNAs will bring the amino acids in the correct order according to the template mRNA. Each 3 bases codes for a single amino acid, the amino acids are brought to the ribosome, and a condensation reaction combines each amino acid, this will continue until a stop codon is reached.
