Welcome to the NCERT Solutions for Class 12 Biology - Chapter Molecular Basis of Inheritance. This page offers a step-by-step solution to the specific question from Exercise 0, Question 6:
During DNA replication, why is it that the entire molecule does not open in one go? Explain replication fork. What are the two functions that the
monomers (d NTPs) play?
During DNA replication, why is it that the entire molecule does not open in one go? Explain replication fork. What are the two functions that the
monomers (d NTPs) play?
While replicating the entire DNA molecule to keep the whole molecule stabilized does not open in one go because it would be highly expose energetically. Actually unwinding creates tension in the molecule as uncoiled parts. Helicase enzyme acts on the double strand at ori site of DNA and a small stretch is unzipped also called unwind. Immediately, it is held and stabilized by single strand binding proteins. And the exposed strands are copied as a point of unwinding moves and ahead in both directions. Then it gives the appearance of Y- shaped structure which is known as replication fork.
Two functions of monomer units of NTPs are as follows:
