Document Summary
Chapter introduction: every protein is assembled on ribosomes according to instructions dictated by genes coded in dna. Instructions encoded in dna and leading through rna to the sequence of amino acids in a protein. 13. 1 the connection between dna, rna, and protein: proteins are encoded by genes made of dna, molecular steps needed to go from gene to protein: transcription and translation. Frank crick gave name - central dogma - to the flow of information from dna to rna to protein. In transcription: enzyme rna polymerase creates an rna sequence that is complementary to the. Separated transcription and translation in eukaryotes: difference - prokaryotic cells can transcribe and translate a gene simultaneously, eukaryotic cells transcribe and process mrna in the nucleus before exporting it to the cytoplasm for translation on ribosomes. Uuuuuu artificial mrna resulted in a polypeptide containing only the amino acid phenylalanine - uuu must be the codon for phenylalanine.
