Question
Chapter 25, Problem 25.64P
Interpretation Introduction
Interpretation:
Interpret quaternary structure of helicase.
Concept Introduction:
Helicases is an enzyme responsible for the unwinding of the DNA double helix model to create single strand of Dna.
Helicases helps in breaking or degenerating the hydrogen bonds present between the bases such as 2 bonds between A and t while 3 bonds between G and C. All this process is taking place for the purpose to make DNA strand ready for replication.
