Extra Credit (7th grade)

During December and January, we will be studying genetics and heredity in science. Since both of these concepts involve DNA, it is important to learn about the structure of it.... To further understand these concepts, it would be helpful for you to make your own 3D model of DNA. By doing so, you will have the opportunity to earn up to 25 extra credit points.

Requirements:

Must be neat and show accurate detail of the nitrogren bases, phosphates, and sugars

All words spelled correctly

Each component of DNA has its own color

Each component of DNA has a label or is represented on a key

There are at least 4 phosphates on the model

There are at least 4 sugars on the model

It is obvious by shape that Adenine only fits with Thymine, and Guanine only fits with Cytosine

There is one full obvious twist in ladder shape

There are at least two Thymine components

There are at least two Adenine components

There are at least two Cytosine components

There are at least two Guanine components

The model is three-dimensional

The model shows DNA unzipping and rezipping

The model shows the enzyme in its proper place

Right, then.

Who out there can do this??
