The Central Dogma Fill in the arrows with the correct process.Word Bank:TranslationTranscription Transcription Translation Comparing Compare transcription and translation by placing the facts in the correct column. Transcription Occurs in the nucleus of a cell Requires RNA polymerase DNA to RNA Produces an mRNA Translation Occurs in the ribosomes of a cell RNA to Protein Produces a polypeptide chain Putting It All Together: Transcription and Translation Use the codon chart to transcribe and translate the following DNA sequence:**Remember** First you must transcribe DNA into RNA.

Step 1:mRNA strands are transcribedfrom DNA in the nucleus of the cell, because the DNA is too big to leave the nucleus. The process of synthesizing a protein is called translation. In other words, it translates the message carried on the mRNA into proteins. This occurs at ribosomesin the cytoplasm of a cell. Step 2:The mRNA must be translatedinto a protein. mRNA is read threeletters at a time, this three letter pair is called a codon. tRNA brings amino acidsthat match the codons from the cytoplasm to the mRNA. The Amino Acids then bind together to form a protein.
