81. HSP 90:

♤ Recently scientists discovered a potential silencing mechanism: Heat shock protein 90 (HSP90).

♤ HSP90 keeps the genetic mutation under check in normal circumstances .In stressful situations reservoirs of HSP90 get depleted allowing the genetic mutation to manifest as a trait.This allows the organism to quickly adapt to changes in environment.

♤ The research team has used HSP90 to explain the adaption to pitch blackness in cave blindfish.
