Week of 11/18- 11/22
Monday – 11/18 – Academic study hall – period 7 – * Call on Drosophila Lab
1: DNA Activity – this was done as HW!
a) Reviewed important structural aspects of DNA
b) Students makes 2 dimensional cutouts of 6 nucleotides.
c) Labeled Nucleotides, Direction, and code on the cutout that student keeps as notes.
2. Part 2 – Model building (3 dimensional models)
a) Add to Student DNA presentation (linked last week) by identifying the nitrogenous bases
take picture of 4 nitrogenous bases (models) and identify on the presentation.
Monday – 11/18 – Homework:
End of Monday…
Tuesday – 11/19 – period 7/8 – LAB!!!
1: Thomas Hunt Drosophila Experiment (#1) – Sex- linked!
What was important about this experiment was that is was the 1st time that an allele was associated on a particular chromosome (the X chromosome). It was the 1st evidence of the chromosomal line of inheritance and although it used parts of Mendelian genetics (dominant and recessive alleles) it also demonstrated that the Law of Independent assortment was not always the case. THERE ARE SCENARIOS where alleles travel on the same chromosome! This is not rare as we have 30,0000 genes in our human DNA and only 23 different chromosomes!
Most genes are linked. Mendel was lucky to pick alleles on pea plants that were not linked so that he could establish the Punnet Squares and the laws of probability that result from unlinked alleles.
2. Finish DNA activity –
a) Build the DNA molecule!
Work on DNA Activity – Part 2 – Model building (3 dimensional models)
Your work on the DNA Activity will be completed on the the linked Presentation that you have been using since last Thursday.

2: Please view the three college lectures to answer the questions from the form below.
THE FORM WILL DIRECT YOU TO EACH VIDEO!
College Lecture 1:
College Lecture 2:
College Lecture 3:
End of Wednesday…
11/21 – Thursday – period 7/8 Lab!
*Review the idea of linked genes from Wednesday..
1. Take picture of the Class DNA, made from all the student group DNA segments.
This the last slide of the DNA activity. You also need the Code!!!!
2. Sordaria Fimicola Lab – begin – note taking in Marble Notebooks!
3. Set-up the Sordaria Firmicola agar plates
We are culturing 2 types of fungi (decomposer), Tan – mutant and Brown – wild type. We put them in four alternating quadrants in the petri dish so that the mutant and wild type will sexually cross to make hybrids. We then placed the petri dishes in the incubator (38 degrees Celsius) for about a week so that we can take samples of the hybrids and view the hybrids ascospores (group of eight spores). The color of the fungi is due to the color of the ascospores and we will determine the crossover percentages by viewing the pattern of the ascospores (tan or brown). I will explain this completely again when we get to the next phase in this lab.
4. “VOICE OVER PROJECT” – DNA replication
“VOICE OVER PROJECT” – DNA replication
Your group will make a story board of all the steps of DNA Replication.
Please place a screenshot of the video into a new page of the Google Doc and add as many screenshots of the animation as necessary to completely and thoroughly describe the video using captions that you will synthesize from your text book.
Link to video file for “VOICE OVER PROJECT” – DNA replication”
You will need to use your text pages 313 – 318 to help learn all the important steps of DNA replication. Whenever you use an important vocab word please bold it and add its definition below the caption. Presentation counts and well as content.
So you will need to make screenshots of the video that you will open on your computer. These screen shots will be placed into the Google Doc THAT I SHARED WITH YOUR GROUP. Each screenshot will have words below it that you will makes with your group (using the textbook) to describe the step in the replication of DNA. Make as many as slides as possible to describe the entire process.
Work together by adding comments and chatting by clicking comments above. Do not let the LVP off the hook. Get them involved. Everyone is responsible for understanding the content. This graded project will be based on presentation, content, and accuracy. Humor is appreciated but accuracy is still important.
Look for the link for the google doc for each group THAT I JUST SENT Today. It is already linked by each lab group. Check your private email (gmail) account!
11/21 – Thursday – Homework

Please download the following file:
Blank DNA Replication video VOICE over.mp4
In this activity you will bring your slides that you made from your Google Docs with their corresponding captions to your Lab Group. You will assimilate the information into your team in order to create an actual voice-over that is appropriate and in sync with the animation through Imovie on your Laptops. Your Team with create a movie with this voice-over added and will air drop it to me.
11/22 – Friday Homework –
1. Please make a second response to the DNA duplication form.
2. Fix your DNA Replication Storyboards!!
Most groups neglected to read the directions and did not include a vocabulary section!
This excerpt is from the instructions above (from Thursday) and from the shared doc:
“You will need to use your text pages 313 – 318 to help learn all the important steps of DNA replication. Whenever you use an important vocab word please bold it and add its definition below the caption. Presentation counts and well as content. “
3. Make sure that the Brine Shrimp Lab is completed. I am going to grade it soon. I will not be reading labs prior to grading. You should know what I expect and those guidelines were posted at the end of week 2 in the second quarter.
4. Please complete the form below on Morgan’s second ground breaking
Drosophila experiment. Do not lose sight that what we are studying this weekend has
everything to do with replicating DNA (in the S1 of the life cycle of the cell) before meiosis!
End of week 3!!!!
