This lesson plan was created based on a template developed for the Curriculum, Instruction & Assessment initiative sponsored by the Alliance for Catholic Education.
Number of Days:
SWBAT transcribe a DNA sequence and translate an RNA sequence.
SWBAT apply the process of translation to analyze mutations in a gene.
Benchmark or Standards:
B.1.23 Understand that and describe how inserting, deleting, or substituting DNA segments can alter a gene. Recognize that an altered gene may be passed on to every cell that develops from it, and that the resulting features may help, harm, or have little or no effect on the offspring’s success in its environment. B.1.26 Demonstrate how the genetic information in DNA molecules provides instructions for assembling protein molecules and that this is virtually the same mechanism for all life forms.
Projector, laptop, X-men video
open-ended questioning (X-men), predicting before concluding
Changes for Next Time:
|Time||Learning Task||Method or Procedure|
|10||Students are given a strand of DNA, and they must transcribe and translate this strand. Then, they must change one base on that strand, and transcribe and translate this new sequence. What do you notice?||Bellwork|
|4||Discuss bellwork||class discussion|
|3||Explain the different types of DNA mutations||Notes|
|4||Predict the consequences of different DNA mutations on the amino acid sequence. If you substitute a DNA base pair, will the amino acid always have the same change?||Brainstorm|
|20||Explain how the mutations in DNA result in different amino acid mutations. Use a graphic organizer showing the original DNA strand, the DNA mutation, the RNA strand, and the Amino Acid strand||Graphic organizer, questioning|
|2||Is a DNA mutation ALWAYS bad?||Exit card|
|Day 2|| || |
|3||BW: Do you think it is possible to create X-Men from mutations? (Show video clip of X-men that describes how they were the result of "mutations")||Bellwork|
|4||Discuss BW: begin to focus on the idea of how mutations may or may not effect an organism, and the extent to which they may cause change in the phenotype of the organism.||Discussion|
|45||Transcription, translation, and mutations worksheet. Students will be given DNA sequences to transcribe and translate. Then, they will make DNA mutations and analyze the effect of these mutations on the amino acid strands.||Pair-work|
|HW||HW: Study for quiz on transcription, translation, and mutations|| |
|Day 3|| || |
|5||BW: Review for quiz, finish going over the pair-work from yesterday||Bellwork|
|40||Quiz||Independent & Individual|
|7||Answer questions from the quiz||Class discussion|
Here the lesson author can reflect on changes for future years. After executing the lesson in the classroom, the member can edit this section of the wiki resource to describe changes for making the lesson more effective next time
What Worked Well:
After executing the lesson in the classroom, edit the wiki resource to highlight particularly effective activities or assessments for reference in future years.
