A Chick Video!

Hi Students!  I've been grading IA's for 2nd year and it's driving me bananas, so here is a video of the growing chicks.  Listen to their cute little peeps!  Their grown up sisters are squawking in the background.  I'll include a photo of them too, so you can see where all the noise is coming from.  Apparently I was supposed to be paying more attention to them!  Hope you all are hanging in there!

Video Update for March 20, 2020

Good Morning Students!  Here is today's video.  In brief, what it says it to keep those 2.7 and 7.1 questions coming in, but you can forget the 2-3 paragraph response (I know that I said 2-3 pages by accident in my video!) to the epigenetics video and the dbq's.  Stay tuned for some instructional videos on Transcription and Translation.  Also, I said that we got 18 chicks, but it is actually 16, and they are so cute!  Photo included below.

Baby Chicks!

Hi Students! First Video

Hello Students:

My first video to you is below.  In summary:

1. Review DNA Replication (notes and some videos are on my website
2. Finish 2.7 and 7.1 Questions in your notebook and email me a photo (mkenny@pps.net)
3. Read 7.2 and go over Transcription Notes
4. Watch "Epigenetics the Hidden Life of Our Genes" and the 8 minute clip from "Ghost in our Genes" .  Write a 2-3 paragraph summary of what you learned about epigenetics and how it relates to transcription.  
5. Do DBQs on pp 356 and 358 in 7.2.  You can put the answers at the end of your 2-3 paragraph document.  Submit both the paragraphs and dbqs to the assignment in turnitin.com by Friday 3/20
6. Read the transcription and translation sections of 2.7.   I will put a genetic code worksheet on the website to work on.

Update of What We Have Covered and Will Cover

• Tues 3/10:  Science State Testing.  Thank you all for being so cooperative with this!  I'm not sure how this will get finished in light of corona virus, but I'm assuming that extensions will be made and you will be pulled out to finish it later when we get back to school.
• Thurs 3/12:  Go over the Hershey-Chase experiment and notes on DNA Replication.  Work on the 7.1 questions that I put on the website.  Get checked off when you finish.
• Mon 3/16:  Review DNA replication.  I have put several videos on this website to help you go over the process.  Finish doing the 2.7 and 7.1 questions in your notes.  You can email me a photo of this work and I will check it off.  Read 7.2 and go over the Transcription Notes.  
• Wed 3/18:  Watch the Video "Epigenetics: The Hidden Life of our Genes".  It is 53 minutes.  We used to show "Ghost in Your Genes" as the primary video on epigenetics and I have also included an 8 minute clip of that.  Please watch these and write 2-3 paragraphs about how epigenetics works and how it relates to the topic of transcription.  I would also like you to include answers to the 2 DBQs in 7.2 on twin studies.  Please submit these to turnitin.com by Friday 3/20!
• Fri 3/20:  Read the transcription and translation sections of 2.7 (pp 116-122) and do the Genetic Code worksheet on my website.   I will post a video to help you get started on this.  
• Moving forward:  Read 7.3 and go through the Translation Notes.  I will post videos to help with this material.

2.7 and 7.1 Work to be Done after the Genetics Test on Friday 3/6

1. (Starting in 2.7) What does it mean to say the DNA replication is semi-conservative?
2. Read the section on the Meselson-Stahl experiment, describe the evidence, and explain what it means.
3. Do the DBQ on pp 113-114
4. What does helicase do?
5. What does DNA polymerase do?
6. (Moving to 7.1)  What were Hershey and Chase trying to determine in their experiment?
7. Outline the Hershey-Chase experiment, including the results.
8. What is a nucleosome and what is its role in DNA packing?
9. Do the DBQ on p. 349 (this one is tricky, but I will give some background on it in class)
10. Outline the process of DNA replication.  You may draw a diagram.  (We will go over this in class).
11. What direction does DNA replication go and why is it limited in this way?
12. What are some of the functions of non-coding DNA?
