Protein synthesis in simple terms. I cover the steps of transcription and translation. The overall process involves DNA unzipping when RNA polymerase attaches and a strand of RNA is created. Rna is different than DNA because it contains the base Uracil instead of Thymine. This step is called transcription. I next show the difference between transcription and translation by showing how the mRNA leaves the nucleus and attaches to a ribosome. At the ribosome codons and anticodons put the amino acids together in the correct order to form the protein. Translation Practice • How to Translate mRNA to Amino Acids
