Document Summary

Synthesis of rna using information in the dna. Carries a genetic message from the dna to the protein-synthesizing machinery of the cell. Synthesis of a polypeptide using the information in mrna. Complex particles that facilitate the orderly linking of amino acids. Genetic instructions for a polypeptide chain are written in the dna as a series of nonoverlapping three mononucleotide words. Provides patterns for sequence of nucleotides in an rna transcript. An enzyme that separates two strands of dna and joins together. Rna nucleotides complementary to the dna template strand. The dna sequence where rna polymerase attaches and initiates. The strip of dna that is transcribed into an rna molecule. After rna polymerase binds to the promoter the dna strands unwind and the polymerase initiates rna synthesis at the start point on the template strand. The polymerase moves downstream, unwinding the dna and elongating the rna transcript 5-3. The rna transcript is released and the polymerase detaches from.
