Orbit DNA–RNA Transcription Model

DNA–RNA transcription model designed to demonstrate base pairing and double helix structure.

This interactive molecular model supports clear understanding of how DNA is transcribed into RNA, making abstract molecular biology concepts more accessible for students. By allowing the DNA strands to be assembled, separated, and reconfigured, learners can actively explore transcription processes rather than relying solely on diagrams. Well suited to senior secondary and tertiary biology teaching, it is ideal for classroom demonstrations, group activities, and practical learning sessions.

Key Features

• Interactive DNA–RNA model illustrating the transcription process
• Displays one full turn of the DNA double helix using 12 base pairs

• Detachable DNA strands to demonstrate RNA transcription step by step
• Suitable for GCSE, NCEA senior biology, and advanced level study
• Includes support stand, instructions, and RNA transcription activity
