2 DO NOW

3 TRANSCRIPTION TRANSLATION mRNA CYTOPLASM NUCLEUS CYTOPLASM PROTEINS AMINO ACIDS

4 2007-2008 FLOW CHART  TRANSCRIPTION/TRANSLATION http://www.youtube.com/watch?feature=player_embedded&v=NJxobgkPEAo From RNA to Protein Synthesis - YouTube NUCLEUS CYTOPLASM RIBOSOME DNA mRNA rRNA tRNA RNA polymerase Amino Acid Polypeptide chain [PROTEIN] TRANSLATION TRANSCRIPTION

5 FLOW CART TRANSCRIPTION TRANSLATION ---------------------------------------------------------- NUCLEUSCYTOPLASM RNA polymerase mRNA [code] tRNA [interpret] polypeptide chain / PROTEIN rRNA a.a

6  TRANSCRIPTION/TRANSLATION

7  PROTEIN PROTEIN STRUCTURE

8 12.4 GENE REGULATIONS and MUTATIONS  WHAT YOU WILL LEARN -prokaryotic/eukaryotic gene regulation -types of mutations & results -mutagens

9 READING Q’s 1-Like DNA code, the following sentence: “The dog ran” contains only 3 letter words -INSERT a “z” after “Th”—rewrite the sentence: Thz edo gra -WRITE the sentence again inserting an additional letter Thz zed ogr -What happens to the sentences as you add letters? become nonsense

10 READING Q’s 2-DESCRIBE point mutation -single nucleotide/base pair is changed can cause a genetic disorder

11 READING Q’s 3-NAME -what type of mutation occurs when a STOP codon replaces an amino acid codon -nonsense mutation cause translation to terminate early proteins cannot function normally

12 READING Q’s 4-EVALUATE -Would a 3-nucleotide insertion result in a frameshift?  YES  NO -EXPLAIN -insertion of a nucleotide shifts an entire 3 code sequence—shifts amino acid sequence X

13 READING Q’s 5-RECORD The mRNA sequence/sub A for G -AUG–AAG–UUU–GGC – ACA – UUG-UAA

14 READING Q’s 6-COMPLETE table: frameshift / substitution -substitution -frameshift

15 READING Q’s 7-EXPLAIN how UV light damages DNA -links thymines—forms a “kink”

16 READING Q’s 8-DETERMINE -what a mutation can do to a body (somatic) cell -cell death -cancer cell

17 READING Q’s 9-DISCUSS why a mutagen can have longer lasting effects in a sex cell than a body cell -mutations in sex cells are passed on to their offspring -mutations in body cells are not inherited
