what is viscosity and what effect does heat have on the viscosity of DNA? What is the underlying cause of the change?​
tino4ka555 [31]

Answer:

Please find the definition of viscosity, effect of heat on DNA explanation to this question below

Explanation:

Viscosity is a term used to describe FLUIDS, which includes liquids and gases. Viscosity refers to the ability of a gas or liquid to resist flow. In other words, it is the measure of the internal friction that exists between the molecules of a fluid, which resists its flow.

DNA in its natural state exists in a liquid solution, hence, when HEAT is applied, the heat causes ITS MOLECULES to MOVE RELATIVELY FAST and as a result the molecules lose the friction between them and begin to flow. Based on this, heat is said to make DNA LESS VISCOUS i.e. to flow more rapidly.
