DNA recognition, molecular model
DNA recognition. Computer model showing MyoD transcription factor, from a mouse (mus musculus), bound to DNA. Transcription factors are proteins that bind to specific sequences of DNA (deoxyribonucleic acid) and control the transcription (transfer) of genetic information from DNA to RNA (ribonucleic acid). Transcription is the first step in the expression of genes but the correct DNA sequence must first be recognised. Here the two domains of MyoD (left:purple and brown, right:pale green and grey) are bound to either end of the DNA sequence (helix running diagonally from middle left to bottom right)

EDITORS COMMENTS
This print showcases the intricate process of DNA recognition through a stunning molecular model. The computer-generated image depicts the MyoD transcription factor, derived from a mouse (mus musculus), bound to DNA. Transcription factors are essential proteins that selectively attach themselves to specific sequences of DNA, thereby regulating the transfer of genetic information from DNA to RNA. In this artwork, we witness the two distinct domains of MyoD: one in shades of purple and brown on the left side, and another in pale green and grey on the right side. Both domains securely bind themselves to opposite ends of the DNA sequence, forming a helix that elegantly runs diagonally from middle left to bottom right. Before genes can be expressed, it is crucial for the correct DNA sequence to be recognized by these transcription factors. This visually striking representation highlights how biochemistry and biology intertwine as MyoD takes control over gene expression by accurately identifying its target within our genetic material. The space-filled molecular model beautifully captures the complexity involved in this biochemical process. Through this mesmerizing illustration provided by Science Photo Library, we gain insight into how proteins like MyoD play an indispensable role in controlling our biological makeup at a fundamental level – ultimately shaping who we are as living organisms.
