Document Summary

Not all polypeptides become enzymes: broadly, describe the difference between transcription and translation. Transcription: dna messenger rna(mrna), nucleotide sequence nucleotide sequence, Same language (except t = u in mrna) Dna sequence of gene that regulates expression (on/off). Terminates 10 35 bp after this mrna sequence: explain what introns are. Intervening sequences, noncoding regions that are cut out and spliced while in the nucleus. Introns are then spliced, cut out because they are not a part of the coding sequence. What is the function of transfer rna & how is it carried out? trna carry specific amino acids on one end and an anticodon at the other end to match up with the proper codon of mrna c. Act as a zipcode to direct the transport of the polypeptide to a particular organelle: describe the different kinds of point mutations. Base pair substitution and insertion/ deletion frameshift mutation. Silent has no effect and missense has little to a major effect.
