Answer :

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.
