Explore the fascinating process of protein synthesis, where mRNA transcribed from DNA guides the creation of a polypeptide chain with the help of tRNA and ribosomes. This text uses a Candy Factory Analogy to simplify the complex steps involved in protein synthesis.
E N D
Types of RNA(Pg 65) • List and explain the 3 kinds
mRNA transcribed from DNA mRNA exits through nuclear pore to cytoplasm/ribosome tRNA binds to amino acids Loaded tRNA bonds mRNA at ribosome Polypeptide chain grows in response to mRNA codons Completed protein either used by cell or is packaged and exported Boss gives recipe to messenger Messenger leaves office through door; goes to factory floor and to workstations Workers pick up ingredients Workers assemble ingredients at workstation Ingredients are combined according to recipe Candy assembly finished; workers eat some, rest is wrapped for shipment Candy Factory Analogy
