What a week! I am so proud of my students for staying on track and doing an outstanding job presenting their DNA Replication projects to the class. Students who did not present this week are expected to present at the beginning of class on Tuesday. Today we learned about the Central Dogma concept (Lesson 4). We explored how introns are excised from mRNA by the spliceosome and the resulting mRNA exits the nucleus and is translated into protein by a ribosome. Students received a set of notes to use for review and which should be very helpful in completing the Central Dogma Crossword Puzzle. The crossword puzzle is due next Thursday (January 30). Students who would like to extend their learning about introns should consider reading “New Genes Spring, Spread from Non-Coding DNA” and share your learning with the class!
As a reminder, the DNA Base Pairing Worksheet was due today.
This lesson is all about the Central Dogma: DNA makes RNA makes protein. Review the lesson (Genetics Unit Lesson 3) and complete the worksheet (DNA_base_pairing activity) to demonstrate mastery of this challenging concept. Remember: Monday is the Martin Luther King, Jr. holiday so we will not have school until Tuesday. You will have the weekend and all day in class to complete your DNA Replication projects. Use your time wisely! Be ready to present your learning to the class. Groups will have at least 5 minutes to share their work and answer questions. Also, the Biology Task Golden Ticket deadline has been extended to February 14. Upload your drafts to Ms. H’s Dropbox folder or email them directly to me for feedback.
Please review Genetics Unit Lesson 2 to learn how DNA copies itself. Note the complex molecular machinery required to simultaneously copy DNA in both the 5′ to 3′ direction, as well as in the 3′ to 5′ direction. For more on the mechanism, read about Okazaki fragments.
Remember, the Biology Task was due yesterday, so please see me if you have not yet submitted your final draft. Also, the DNA transcription project is due this Friday.
Big day today! Tasks are due – please submit to Ms. H’s Dropbox account in your designated class folder. Students who need additional time must check in with me to create a plan for success.
We are starting a new unit on genetics today. Why genetics? Because a thorough understanding of genetics is central to understanding biology today. To discuss heredity, evolution, medicine, and biotechnology, we need a common understanding of genetics. Please review our first lesson (Genetics Unit Lesson 1 140113) and work together with your project teammates to complete the Genetics Unit Assignment 1 by this Friday.
Reminder: the final deadline for the completed final draft of the Task is Monday, January 13. The grading rubrics are available in Ms. H’s Dropbox folder.
Here are the slides from class on January 9, 2014.
Day 1 – Period 1
As of January 2014, I am very excited to assume teaching responsibilities for Ms. H‘s high school biology students. Our first unit will be Genetics, and we will learn about nucleic acids (DNA and RNA), cell division, and heredity. I strongly encourage my students to sign up for Khan Academy and view the Heredity and Genetics videos. Then challenge yourself with TED-Ed Lesson in the genetics category!
