Prepare models of DNA and RNA using locally available materials and present them in a science exhibition.

It is quite easy to make models of DNA and RNA using some very easy to get materials.

Things you need to require for these models are as follows:

1. Wires: Since they are flexible you can easily mould them and this wire will act as the strands.

2. Beads: Beads of different colour can be used as representing different nitrogenous bases.

3. Coloured sticks or ribbons: They can be used to represent the hydrogen bands between the nitrogenous bases.

4. Wooden block or piece of thermocol: This can act as the base of the model.
