Cell Division and DNA

We are going to continue our work with Cell Reproduction.  Specifically we are going to look at DNA and how it makes up the chromosomes in your body.

The following are two great readings on DNA.
1. Science for Kids Link- DNA
2. Kidipede - Genetics for Kids


Here is a link to an interactive site on DNA:
1. Tour of the Basics  - from the University of Utah - Choose "What is a Chromosome?"
2. DNA Base Pairing- Interactive.

Here are two good videos explaining the relationship between DNA, genes, histones, chromatin, chromatids, and chromosomes.

Structure of DNA

Here is the video on Chromosome wrapping and DNA Synthesis
(Watch until 2:55)



Here is the link to the Nobel Prize Game on DNA Replication.


The following is a link to a reading on DNA's structure and composition.

The Guide- DNA's Chemical Composition and Structure.

Here are two images of the make-up of DNA.
In both of these images you can see the "ladder" sides are made up of a sugar and phosphate, where the central rungs are made up of nitrogen base pairs (A,G,T and C).

We will be constructing DNA models using one of the three methods:

• Bead Jewelry
• Origami or
• Candy

The point of the activity is to be able to correctly identify the smaller parts that make up a strand of DNA.

SAMSUNG SOLVE FOR TOMORROW CHALLENGE

We have been chosen as Finalist in the Samsung Challenge!

We will be traveling to Austin, TX for the SXSW Conference to present our work!

Please join us in spreading the word about the invasive European Green Crab an environmental issue that can cause huge impact to Maine's 17 million dollar shellfish industry!

Cell Cycle Simulation

The students worked today on cell cycle simulations using pipe cleaners and background pages.
Using their laptops and Photobooth they were able to take snap shots and import them to a Pages document.

Here are some photos from today's work.

Cell Cycle Online Webquest

Access the webquest by clicking on this link.

You will need to download this as it is a Pages Document.

Cell Division- Mitosis

Here is a great image of mitosis.  This is much like our text book but do not worry about the "Prometaphase."

Mitosis is the process of cell division for eukaryotic cells found in multicellular organisms.  All cells come from existing cells and mitosis is how most cells divide. The only eukaryotic cells which do not divide by mitosis are sex cells a.k.a. gametes a.k.a sperm and egg cells. 

Here are some videos that introduce cell division- mitosis.




Here is a video that links cell division -mitosis and cancer.
