What Supplies the Energy That Drives the Relief of Mechanical

Question

What supplies the energy that drives the relief of mechanical strain by DNA gyrase?
A)condensation of ATP
B)condensation of GTP
C)hydrolysis of ATP
D)hydrolysis of GTP
E)a proton gradient

Accepted Answer

DNA gyrase relieves mechanical strain in DNA strands during processes such as replication and transcription by introducing negative supercoils into DNA. This process is powered by the hydrolysis of ATP, not by condensation reactions, GTP hydrolysis, or a proton gradient.
