Today in class we reviewed the process of transcription and translation by looking at this Candy Factory analogy. Transcription is the process of making a copy of DNA into messenger RNA by RNA polymerase. The DNA is unable to leave the nucleus but mRNA can. This is great because the RNA must take this copy to the ribosomes which are either free floating in the cytoplasm outside the nucleus or attached to the endoplasmic reticulum. It is here at the rRNA that it can be translated from mRNA into a protein by tRNA. The tRNA reads the stand of mRNA 3 bases at a time and then brings the corresponding amino acid. Those amino acids continue to grow in a chain as the strand is read and then broken off to form a protein. We completed this DNA Translation practice in order to understand how to translate DNA into mRNA and finally into a protein. It can all be viewed by looking at this Translation picture which we had reviewed last time.
