Last year, John Hopkins renamed a research building on their campus after Henrietta Lacks. Here is the article.
In this activity, PBS students will listen to a Radiolab production about Henrietta Lacks and the HeLa cell culture that was derived from her tumor. Listen here. They will also read an article her and the development of the cell culture, found here.
Last year, John Hopkins renamed a research building on their campus after Henrietta Lacks. Here is the article. MI students opened the week with the unit quiz on 3.2. We will start unit 3.3.1 tomorrow with some short skits about cancer treatments, and then explore a lab about prosthetic limbs.
PBS students are assembling karyotypes with an online tool from the University of Utah. We will listen to a Radiolab production about the HeLa cell line and discuss some questions about medical ethics. On Friday, students will take the unit quiz for 3.3. *Any PBS students that are making display boards for HOSA need to bring their boards to the classroom by the end of the day on Thursday 2/28. Seniors will critique them during first hour on Friday 3/1. The third quarter is wrapping up. After today, we will only have nine days left.
If you are missing any assignments, the last day to turn them in for partial credit is Thursday 2/28. Herd immunity is the idea that as long as enough people within a population are immune to a disease, they can indirectly protect those who are not immune. It's particularly important for people who are unable to get vaccinated. In this video, Dr Adam Kucharski briefly explains how it works.
When the percentage of the immune population falls below the level defined by the basic reproduction number, it can result in an outbreak, like the one that occurred in France in 2018. HOSA Announcements:
*There will be a meeting in G117 on Thursday (2/21) at 2pm to talk about the state conference. *Poster Critiques are being pushed back one week. PBS students who are doing a display for the state conference need to bring said display to G118 on Thursday (2/28) by the end of the day. On Friday morning (3/1), BCA seniors will critique the displays and provide feedback. MI students are wrapping up unit 3.2 with activities on virology and routine screenings. The quiz for unit 3.2 will be early next week. PBS students using paper models to visualize the processes of mitosis and meiosis (see below for crash course videos), then constructing a concept map with the vocabulary associated with inheritance. On Friday (2/22) they will have class time to work on HOSA projects. Crash Course #12 Crash Course #13 In observance of Presidents' Day, here's a presidential trivia question. What is the most common US presidential first name, and how many presidents are there, who had that name? Week of Feb 11 PBS students will finish unit 3.2 and take the unit quiz on Tuesday. There will be two questions in which you are given a sample DNA sequence and asked to transcribe it it into mRNA, and then translate it into an amino acid chain. The condo chart from 3.2.2 will be provided on the quiz and is also pictured below. If you have any uncertainty in the use of this chart, PLEASE ASK. MI students are turning in 3.2.3 and circling back around to the yeast lab for 3.2.2. We will grow some wild type yeast and mutated yeast with increased UV sensitivity on a couple different agar plates, and find out how effective various types of sunscreen are at protecting the cells from UV damage.
Base pairing in DNA
Cytosine pairs with Guanine: C with G, round letters together Adenine pairs with Thymine: A with T, straight line letters together Base pairing in RNA Cytosine still pairs with Guanine, but Adenine is hooking up with Uracil behind Thymine's back. Hydrogen Bonds Cytosine and Guanine share three bonds: 3 is round like C and G Adenine and Thymine share two bonds: 2 has a straight line like A and T Purines vs Pyrimidines Guanine and Adenine are purines: If you saw a kitten (that purrs) you might say "GA! It's so cute!" Thymine, Uracil, and Cytosine are pyrimidines: TUC sounds like TUT As in King Tut Who was from ancient Egypt Which is famous for pyramids Which sounds like PYRIMIDINES! A couple of web resources for the MI activity on breast cancer screening and prevention are no longer available. Here are some alternates:
1. NOVA's A Family Disease 5. Hereditary vs Spontaneous Cancer 20. Exercise to reduce risk of breast cancer Week of Feb 4
MI students are finishing 3.2.1 with notes and short presentations about cancer risks and prevention strategies. On Tuesday, we will begin a lab that tests the effectiveness of different sunscreens using yeast. Hopefully the mutated yeast won't gain superpowers. Update 2/6/2019: The yeast for the stock plates isn't ready yet, so we are putting this activity on hold until next week. PBS students will do a lab activity on transcription and translation, using paper models of DNA and RNA. |
