The most interesting topic of my Biology book is Mechanism of DNA replications.
Mechanisms of DNA replications are:
1.Activation of Deoxyribonucleotides: They occur freely in the nucleoplasm.
They are of four types-deAMP,deGMP,deCMP and deTMP.
2.Exposure of DNA strands:Enzyme helicase acts and opens the two strands of DNA . The whole strands however does not opens at one stretch but the point of separation proceeds slowly towards the direction hence giving it a Y-shaped structure called replication fork.
3.RNA Primer: It is essential for the formation of new DNA chains.
4.DNA Polymerases: Prokaryotes have three major types of DNA synthesizing enzymes called DNA Polymerases III, II and I. All of them add nucleotides in 5'-->3' direction on 3-->5 strand.
5.Base Pairing: The two separated DNA strands in the replication fork function as templates. Deoxyriboribonucleoside triphosphates come to lie opposite the nitrogen bases of exposed DNA templates.
6.Chain Formation: It requires DNA Polymerase III in prokaryotes and Polymeraseδ/ε in eukaryotes.
7.Proof Reading and DNA repair: A wrong base is sometimes introduced during replication. The frequency is one in ten thousand. DNA Polymerase III is able to sense the same. It goes back, removes the wrong base, allows addition to proper base and proceeds forward.
It also gives us knowledge of human, plant and animal anatomy.

Intresting thing about science which I like as per my book is abiotic environment
oh thats nice :)

the most interesting topic is the experiments and the facts column.The book which have more of these are very interesting and more knowledge can be obtained from them.
