The small DNA/RNA model shows the double helix and how the molecules split at the centre of the base pairs. It includes:

• 30 coloured tubes – Guanine red, cytosine green, thymine blue, adenine gray and uracil white
• 12 white two prong centre representing the hydrogen bond between the base pairs
• 28 black trigonal atom centres showing sugar
• 25 red two prong atom centres, which represent phosphate groups
• 50 yellow tubes that link the phosphate groups to the sugar rings
