Kelly is off from school since its Summer vacation, so she decides to help her father with building a tree house for her younger siblings
In order to build a tree house they needed Instructions and Kelly realizes the instructions (which is the DNA) inside the house (thats the nucleous). But transcription are the instructions in order to make a tree house.
Kelly (who is the mRNA) goes inside the house and gets the instructions then runs back outside to start building with her dad.
They gather the wood (ribosome) and start building. Kelly's father hands her tools (tRNA) which is how translation occurs.
Now that the tree house (protein) is done Kelly's brother and sister are very happy.
