Presentation Transcript

  1. Quick Write (5 min.) • Why do you think the library holds some books for reference only? • If you cannot borrow a book, how do you take home the information in it? • DNA does not leave the nucleus yet it controls the activity of the cell. How?

  2. Plan for February 25th • Review DNA • What is RNA? Chapter 13.1 • Progress Report and Test Grades • Forecasting (4th Period) • Turn In Stuff! • Coursework Packet • Strawberry Lab

  3. Vocabulary Jigsaw Facts description characteristics Define it What it is NOT. What it is: Word in the middle

  4. Vocabulary Jigsaw Part 1 Do: Students with the same are your Expert Group. In your Expert Group, define the word and make a poster for the word. Finish By: 10 minutes total. (Probably not enough time to make it pretty!) When Done: Get it approved by the teacher. We will be using these in a Gallery Walk. Highlighted Word

  5. Vocabulary Jigsaw Part 2 Do: Visit all the posters to fill in the definitions of the words on the handout. Put: EVERYONE writes EVERY definition on their paper. Finish By: 15 minutes. When Done: Return to your seat and work on Part 2 until time is called.

  6. Part 3: Preview Figures and Tables Do: On page 2, follow the instructions for Part 3. Put: Write in space provided. Finish By: 5 minutes. When Done: Lecture is next. Figure 13.1 Figure 13.2 Figure 13.3 Figure 13.4 The completed packet is DUE on Thursday, 2/27

  7. DNA Review • DNA controls activities of the cell. • DNA • Stores • Copies • Transmits • Shape: Doublehelixformed from • Chains of nucleotides. Heredity Information

  8. DNA Review Label the nucleotide Check your answer

  9. Chap.13.1 Learning Targets • How is RNA different from DNA? • How does the cell make RNA?

  10. Chapter13 How does information flow from DNA to RNA to direct the synthesis of proteins?

  11. Central Dogma • The central dogma of biology is that DNAencodes the information to make RNA. • RNA molecules function together to form proteins. DNA  RNA  Protein

  12. Transcription (in the nucleus) • DNA is transcribed in the nucleus into RNA. Enzymes & proteins unzip the DNA double helix. • RNA polymerase uses one (1) DNA strand to make an RNA copy of that gene. • mRNA is then shipped out of the nucleus into the cytoplasm.

  13. Transcription (in the nucleus) Base Pairing DNA versus RNA RNA has uracil in place of thymine. Ribose in place of deoxyribose. What does the prefix “de” mean? So, how are ribose and deoxyribose different? How can you remember which sugar goes with RNA?

  14. Transcription (in the nucleus) • What is the mRNA formed from the following Template strand of DNA? C C G G A T T A C G DNA Template G G C CU A AU G C mRNA strand

  15. Transcription (in the nucleus) • What is the mRNA formed from the following Template strand of DNA? G G A C T G A T T DNA Template C CU G A C U A A mRNA strand

  16. Transcription (in the nucleus) The DNA is able to be reused to continue producing necessary proteins.

  17. 13.1 RNA Packet • Do: Complete the remainder of the packet. • Put: Write on the packet. • Finish By: We will work on this until 5 minutes to the end of class. • When Time Ends: Progress reports and Test Results. DUE: Completed packets will be stamped during class on Thursday, 2/27.

  18. Grading Day Approaches • Remember, a test score is just one piece of evidence used to compute your grade. • Labs, projects, packets, and participation all factor in to your course grade. • If you scored <69%, see me about making test corrections to raise your grade to passing.

  19. Meiosis & DNA Test Results The revised base points for the test = 35. I dropped 3 questions that performed • Statistics [Raw (Percent out of 35)]: • Mean: 23.7 (68%) • Median: 27 (77%) • Spread: 9.13 Test Grade Cutoffs [Raw Score (Percent out of 35)] • A: 31.5-40 (90% to 114%) • B: 28 - 31 (80% to 89%) • C: 24.5 - 27.5 (70% to 79%) • D: 17.5-24 (50% to 69%) • F: 0-17 (< 50%)

  20. March 7, 2014 is the deadline to make up the test or complete test corrections. • If you were absent—make up the test ASAP. • During 1st Lunch in N221 • In the Testing Center during 7th/8th • Before/After school (pre-arranged!)
