Protein Synthesis: Transcription and Translation Review Central Dogma of Molecular Biology Protein synthesis requires two steps: transcription and translation . DNA contains codes Three bases in DNA code for one amino acid. The DNA code is copied to produce mRNA. The order of amino acids in the polypeptide is determined by the sequence of 3-letter codes in mRNA. DNA vs RNA DNA RNA Sugar: deoxyribose ribose Bonds with Adenine: thymine uracil # of Strands: two one Kinds of RNA Messenger RNA (mRNA) Messenger RNA contains genetic information. It is a copy of a portion of the DNA. It carries genetic information from the gene (DNA) out of the nucleus, into the cytoplasm of the cell where it is translated to produce protein. Ribosomal RNA (rRNA)
