Window Notes

This lesson plan engages students in the processes of DNA replication and RNA transcription. Through a warm-up exercise, students will practice creating complementary DNA strands and transcribing DNA segments into messenger RNA (mRNA). They will learn how mRNA translates codons into amino acids, drawing parallels between DNA and reference materials. Activities include pair-sharing sessions, video snap shots, and guided practice, fostering understanding and retention. This structured approach aims to effectively develop higher-order thinking skills in genetics.

  2. Prior Knowledge-Warm-up--Window 1 • Copy the DNA sequence below and practice the process of replication by creating the complementary strand. Hint: AT&T, cat-guts • DNA: AAT-TGC-ACG-TTA-CCG • Challenger: Create your own DNA segment with 6 nucleotides & the matching complementary DNA segment • Pair/Share----Whiteboard • Be prepared to explain your answer

  3. RNA Transcription**Window Notes

  4. Window Notes Warm-up New Information Develop HOTS ?’s Lesson summary 3-2-1

  5. Objective • Students will transcribe a DNA segment into messenger RNA(mRNA)and then translate the codon to determine the amino acid sequence of that specific protein. • Shared reading

  6. Use for Pair-Share P/S #1 P/S #2 P/S #3 P/S #4

  7. Establish Relevance-Analogy • DNA is like a reference book/encyclopedia in a library • DNA cannot leave the nucleus because it may be damaged • Reference books cannot leave the library because they may be damaged or lost • Pair Share#1: If you need a page from the reference book how can you get it without checking it out? • Sentence Starter: One way you can get the page • from the library is_____________

  8. Create a Video Snapshot foldable with the green paper: 1-Write a question that could be answered by watching this video, at the understand level and above. 2- List 3 facts about the topic. 3-Write a few words to remind you of the most important thing you learned from this clip. 4-Draw a picture or symbol to remind you of the important idea.

  9. Transcriptionvideo Section 12-3 Adenine (DNA and RNA) Cystosine (DNA and RNA) Guanine(DNA and RNA) Thymine (DNA only) Uracil (RNA only) RNApolymerase 1 DNA 2 RNA 4 3 Go to Section:

  10. Complete yourVideo Snapshot foldable……….. 1-Write a question that could be answered by watching this video, at the understand level and above. 2- List 3 facts about the topic. 3-Write a few words to remind you of the most important thing you learned from this clip. 4-Draw a picture or symbol to remind you of the important idea. Pair-share #2: The most important thing I learned from this clip was ____________because____________________ Pair-share/Random call

  11. Messenger RNA mRNA is a Notes: Window 2 • ____________of DNA. • It is allowed to leave the nucleus. • It is a single strand • mRNA has the baseUracil instead of Thymine • Uracil bonds with Adenine (gold=Au & “Ayy You”) • Model: • DNA: ATA-CGC • mRNA: UAU-GCG

  12. “We do”-Guided Practice • DNA #1: AAT-TTG-CGA-CAA • Let’s make mRNA together • mRNA#1: • DNA #2: ATA-GGC-ATA-TTA • mRNA#2 • DNA #3: (class imput) • mRNA #3: • *Whiteboards, random call

  13. Pair Share Partner A: If DNA=AAA-CCC-GAC • mRNA= • Partner B: If DNA=GCG-TAT-AGA • mRNA= • Share your answer and explain which bases A and T bond with and why?

  14. Objective Review • Pairing DNA with a complementary mRNA • DNA: ATA • mRNA: UAU • Is the process of transcribing or transcription

  15. mRNA is made in the nucleus • And released into the cytoplasm of the cell Window 2

  16. RNA TRANSCRIPTION • COPYING PART OF DNA NUCLEOTIDE SEQUENCE INTO A COMPLEMENTARY mRNA STRAND • Step 1- ENZYME-RNA POLYMERASE BINDS TO DNA & SEPERATES 2 DNA STRANDS

  17. STEP-2 RNA TRANSCRIPTION • RNA POLYMERASE • USES 1 DNA STRAND AS A TEMPLATE TO FORM RNA • BINDS TO DNA IN REGIONS KNOWN AS PROMOTERS-------
