Question
Chapter 4, Problem 11P
Interpretation Introduction
Interpretation:
It is difficult to disturb a double helix of DNA if the force holding a helix isweak.
Concept introduction:
Two chains of DNA helix are held together by complementary base pairing of G and C and A and T. Two strands are made antiparallel to make stable DNA.
