• gene is a short segment that contains the information to make a single polypeptide.
• DNA is a molecule that contains herditary/genetic information.
• chromosomes is a tightly packed/ condensed DNA which forms during cell division
• 1. in the nucleus, the message in the gene is copied into an mRNA.
• 2. the mRNA travels to the cytoplasm and attaches to a ribosome.
• 3. as the ribosome moves along the mRNA, it synthesises a polypeptide.
• transpiration is the loss of water through the aeriel parts of the plants, mainly through the stomata of the leaves.
• 4. when the ribosome leaves the mRNA, the polypeptide is released.
• 5. the polypeptide will fold into a protein
