1. Let’s use an analogy of baking a cake to understand it: = -DNA is a large book of recipes(the entire DNA strand) that is too large to leave the pantry(nucleus) in the kitchen(the whole cell). -So a copy of the DNA strand, so therefore a copy of the recipe (mRNA) is written from the DNA strand. This process of copying and writing the recipe on an index card would be (transcription). -The copied recipe on the index card (mRNA), must now leave the pantry (nucleus) and go to the countertop(the ribosome) where it can be read(translation) and the cake (protein) can be assembled. The process of assembling the cake would be (protein synthesis).

2. Well how is the cake(protein) assembled
Well how is the cake(protein) assembled? Ingredients (amino acids) are needed!
So all of the ingredients—the flour, oil, eggs, sugar, water, baking soda, icing (the amino acids), are transferred to the countertop(ribosome) from your helpers the Keebler Elves (tRNA).
One by one the Keebler Elves(tRNA) bring the correct ingredient(amino acid) to the countertop(ribosome) according to what is written on the recipe index card (mRNA). So as the recipe card is read (translation), the cake (protein) is being made!
Later that cake (protein) is baked in the oven (another cell in the body) that needs that cake (protein).
