Step 4;

Now, time for the favourite part of painting. Take your little black paint and colour the strips with a paint brush.

Step 5:

Now, Paper Curling. It is a simple easy way. We just need to fold the strips in a curly way.

The curls would be like this.....Pretty easy!! Isn't it.

Step 7:

Now again cut a strip of chart paper. Now this paper would be used for the purines and pyrimidines.

Step 8:

Then just take your pastels and start colouring.

Here is the coloring rules:

No colour must come in a same row. If you use Red and Yellow in a piece, then you must need to follow coloring red and yellow or yellow and red in a piece. So, I have used Red and yellow [or yellow and red] and Violet and green [ or green and violet].

Step 9:

Start inserting the strips with the help of a glue into the DNA helix without actually disturbing the curls.

Step 10:

Just continue until you finish it off completely.

Tada!! The DNA is ready in no time...

Finished!!
