Window Notes 1-Warm-up 2-New Information 3-Develop HOTS ?’s/Vocab 4-Lesson summary 3-2-1
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
Window Notes Warm-up New Information Develop HOTS ?’s Lesson summary 3-2-1
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
Use for Pair-Share P/S #1 P/S #2 P/S #3 P/S #4
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_____________
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.

Pair-share #2: The most important thing I learned from this clip was ____________because____________________ Pair-share/Random call
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
“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
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?
Objective Review • Pairing DNA with a complementary mRNA • DNA: ATA • mRNA: UAU • Is the process of transcribing or transcription
mRNA is made in the nucleus • And released into the cytoplasm of the cell Window 2
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
STEP-2 RNA TRANSCRIPTION • RNA POLYMERASE • USES 1 DNA STRAND AS A TEMPLATE TO FORM RNA • BINDS TO DNA IN REGIONS KNOWN AS PROMOTERS-------
