Explain how a protein is synthesised

The process starts in the nucleus A gene (section of DNA coding for a protein) unwinds, and the 2 DNA strands making it up unzip Transcription then occurs - one DNA strand is used as a template to make mRNA (which can move out of the nucleus, whereas DNA cannot). This works via complementary nucleotide base pairing (where thiamine is replaced by uracil, hence A binds with U, and C binds with G)This mRNA then moves out of nuclear pores into the cytoplasm to a ribosome Then translation occurs at a ribosome. Here amino acids that match the triplet codes on the mRNA are joined together in the right order via peptide bonds. The protein will then fold into its 3D shape. The protein can then be further modified at the Golgi apparatus, and leaves the cell via exocytosis.
