It all starts with DNA entering the ribosome in a process called translation. The DNA enters and comes out as MRNA. MRNA is a unique because u replaces t. The MRNA then enters the cytoplasm to bond with the RNA polymerase. It then gets fed through the RNA polymers as codons (codes of 5 at a time) and comes out as amino acids. These amino acids then eventually code for larger proteins.
