Unformatted text preview: DNA in the cell is not naked in the cell. When DNA is expressed it is more open. Transcription -Proteins that do the work DNA just sits. RNA polymerase a protein complex that connects to the DNA and makes RNA. Starts in a place called the promoter and ends at the terminator. Makes mRNA has U instead of T. Translation - RNA into a protein small ribosomal subunit then connected to a large ribosomal subunit (ribosome reads in 3letters). tRNA adapter molecules can read RNA and comes with the first amino acid. After taking the amino acid from tRNA the tRNA is thrown out. Start to make a protein chain. Then there is a release factor that ends the protein chain. After tRNA leaves it goes to another process to restore its amino acid. mRNA could produce more than one protein at a time....
