Happy Wednesday Ninjas! Tomorrow is TEST DAY! Journals: Page 35 right: Title: DNA Review Free Form Notes. As you move through the stations, write down any information you feel weak on. Take notes on any helpful tips, tricks, or page numbers you need to study to help your weak areas. FOLLOW ALL INSTRUCTIONS! Do NOT sit at tables Login to quiz (phone or laptop) Spread out around the room (not near anyone) Must earn a Passing Score to enter stations Once in stations, work at your own pace to finish all activities. Pre AP Students: Turn your projects in or have them emailed to me by 4pm today to receive full credit. Late work policy is in effect: Tomorrow it will be a 70, Thursday a 50 and after that….well, you know 

Bellwork: Think, Pair, Share: Which codons would you need to analyze to answer the question in the least amount of time? A AAA CGC ACG B ACC C CCG D Pre AP Students: Turn your projects in or have them emailed to me by 4pm today to receive full credit. Late work policy is not valid since you’ve had a week. Tomorrow it will be a 70, Thursday a 50 and after that….well, you know 

Test is tomorrow: DNA Structure, DNA Replication, Transcription, Translation, Mutations, Gene Expression, DNA Fingerprinting

Stations: 5 minutes each Do everything listed at your table. If, you’re at an empty table work on the review. Ask questions if you’re confused. Rotate when the timer rings Rotations will be clockwise. If you finish an activity at a table, work on the review.

Kahoot Kahoot

Snork activity question… What determines whether or not hair is present on the Snork? What conclusions can we make about the role of amino acids in protein synthesis?

Hair Protein (gene expression): START LONG BROWN STRAIGHT DNA: TAC AAG CCG GCG ACG GTT AGC CTT GAG RNA: AUG UUC GGC CGC Amino Acid Sequence = Hair Protein (gene expression): START LONG BROWN STRAIGHT

Would it change the protein causing a different gene to be expressed? DNA: TAC AAG CCG GCG ACG GTT AGC CTT GAG …if we changed the DNA? Would it change the protein causing a different gene to be expressed? Make a change to DNA in a that causes a change. Is it possible to change the DNA but not see a change?

Debrief: On the back of your Snork paper Which of the following mutations would not change the protein coded for by the original strand? Show your work original strand of DNA: TAC GCA CTA ATT Mutation 1: TAC GCA CGA ATA Mutation 2: TAC GCA CGA ATC Mutation 3: TAC GCA CGA ATG Mutation 4: TAC GCA CGA CTT

TAC GCA CTA ATT TAC GCA CGA ATA TAC GCA CGA ATC TAC GCA CGA ATG Notice that all changes are made in the last codon.. original strand of DNA: TAC GCA CTA ATT UAA Stop Mutation 1: TAC GCA CGA ATA Mutation that doesn’t change the protein is mutation 2 UAU Tyr Mutation 2: TAC GCA CGA ATC UAG Stop Mutation 3: TAC GCA CGA ATG UAC Tyr Mutation 4: TAC GCA CGA CTT GAA Glu
