DNA Structural Transition

Postby mayapartha_1D » Sun Jan 28, 2018 10:47 pm

Can anyone explain what exactly a DNA structural transition is? And its significance to thermodynamics?

A DNA structural transition would be going from a double helix to two separate strands. This would be considered a phase change.

The significance to thermodynamics is that you need to apply heat (+ΔH) by increasing the temperature and are going from a more orderly state to a more disorderly state (+ΔS).

This is the mechanism by which the body begins the process of transcription/translation and is relevant in terms of its endergonic nature.
