Document Summary
Understand and demonstrate diferent steps involved in translaion (cytosol and membrane) Using the codon table, obtain the mrna and amino acid sequence of a given dna sequence. Deine and explain diferent geneic point mutaions and possible mutagens. Relate vesicular transport to cytoskeletal elements previously discussed. Analyse a cascade of event from a primary messenger to a nuclear response, including protein secreion. Translaion-protein synthesis mrna directed protein synthesis is what we talk about. From a mature mrna mrna has a 5" g-gap, a polya tail, introns have been spliced out and it snakes it way out of nucleus through nuclear porins and needs to ind a ribosome. Start codon is aug (met) isn"t found in all proteins, can be cut of. Stops with uaa, uag or uga which don"t correspond with any amino acid. Reads each 3 as a ime and interprets them as a language. Each set of 3 nucleoides is a codon.
