Watch all three videos on DNA replication. 




This DNA replication Song was made by my students in 2007.  They were grade 11 students taking my bio 12 course.  Their music teacher is the same as your band teacher now.

Assignment 5: Answer the following questions in a creative format

1. Why does DNA replication happen?  Give three reasons
2. a. Draw a nucleotide and identify the 5' end and the 3' end
    b. draw a DNA ladder structure and label the 5' and 3 ' end

3.  Compare and contrast DNA and RNA.
a.  What are they made of?
b. What are their nitrogen bases?
c.  What enzymes synthesize DNA and RNA?
d.  How does DNA polymerase join one nucleotide with another nucleotide?

4.  What are the main steps of DNA Replication.  Include details of what each enzyme does
a.  Helicase
b. Primase
c. DNA pol III
d.  exonuclease
e. DNA pol I
f. ligase

5.  In what direction does DNA polymerase synthesize the new DNA strand?
6.  How is the lead strand different from the lag strand?
7.  What is an okazaki fragment?


Creative Formats:  Choose one format
Draw a cartoon in colour.

The Discovery of DNA, a more detailed look at Nucleotides - Assignment 3 and 4

have a look at the notes on DNA, the slideshow on DNA as well as the video explanation of nucleotides and how they fit. Watch my video on DNA





Here is another video from youtube which explains these concepts in more detail.


Two assignments  in MS teams

Assignment 3 - 15 points

SUMMARIZE THE MAIN POINTS OF DNA NOTES 10 points

A. Summarize the main points of the DNA notes AND the DNA slide show in a Cartoon Format and make a clear photo of this cartoon.  upload your assignment in Microsoft Teams.   Include the details about Watson and Crick and Franklin.

EVALUATION rubric
10 points:  You included all the main points in a colourful, creative format which is written in ink and coloured.  You used humour and creativity and your assignment stands out for showing an understanding of the key points

8-9 :  you include all the main points and you show excellence and creativity. your assignment is in colour and inked

5-7 :  you include most of the main points and your assignment is handed in. It is a good start and  You needed more time to finish this.

2-4:  you handed something in that was not quite complete, although it is a pretty good start

You may do Assignment 3 Aas a poem that rhymes if you don't want to draw.

3B.  take a picture of  your drawing of this worksheet filled out: You may redraw it or edit it in Paint.
5 points




Assignment 4. MAKE A MODEL of DNA 10 points
Make a labeled model of DNA in your house. Write your name on a piece of paper and put it in the picture. This must be a pic of a physical model, not a digital model. Make sure that the model is a Right handed helix and not a Left handed one!

10 points:  you made a model and it includes a PAPER SHOWING YOUR FULL NAME in front of it. The model has all the parts and it is labeled. it is easy to see and clear. you made a model that stands out

8-9: you made an excellent model which includes everything asked for. you include a paper showing your full name

5-7 some parts of the model are not complete

NOTE: I WILL ACCEPT AN ORIGAMI ASSIGNMENT. colour it differently than what is on this template:  remember to write your name on a paper in the picture and/or include a pic of yourself, holding it up. https://www.yourgenome.org/activities/origami-dna







Lesson 1 DNA intro. Assignment 1 and 2

Have a look at this introductory video on DNA.  DNA is a code, an alphabet.  Its alphabet has only 4 letters, and these 4 letters can create words, which make instructions for all of life.
In this lesson, you will learn the basic structure of DNA.



I would like you to answer these questions:
In Microsoft Teams, I would like you to find your assignments for this DNA unit.


ASSIGNMENT 1 :  part 1 DRAW DNA
First, draw a labeled picture of DNA that summarizes the main points of DNA.  Photograph this cartoon in a clear picture and hand it in.  your NAME MUST BE CLEARLY WRITTEN ON CARTOON.

The main points are:

1.  DNA is made of nucleotides
2.  The nucleotides are made of sugar, phosphate and a nitrogen base
3.  The nucleotides join together in a ladder structure
4.  The ladder structure is antiparallel.

your rubric
5 points:   your cartoon is brilliant, it includes all main points and it is in colour and inked YOUR NAME IS CLEARLY WRITTEN ON THE PAPER
3-4 :  your cartoon includes all main points and is complete.
1-2: your cartoon is incomplete.

My dear students, we miss you

I know this is a difficult time, but I would like you to know that your teachers miss you and care about you.  

For many of us, Gladstone is our favourite school, and many of us have worked at other school sites.  You are kind, caring, smart, with a beautiful spirit and we are inspired by your presence at Gladstone. 

We can't be on site, but we can be together again in a virtual learning community!  Please  stay tuned here so that I can give you class assignments from my website. You will receive an email from your homeroom teacher at Gladstone. Please reply to that email! 

We want to come together as a learning community again. I hope that you have the resources around you to be safe, to be fed, sheltered, to be at peace and to be connected with those who  love and care for you. 

If you need to contact anyone at the school, such as a counsellor or staff member,  and you are not sure how to do that, please send me an email and I will try to connect you.  

Blessings from home

Ms. Ng
