Question

Choose the correct answer from the alternatives given :
Refer to the given steps Of DNA replication.
(i) Exposure of DNA strands
(ii) Synthesis of RNA primer
(iii) Activation of deoxyribonucleotides
(iv) Chain formation
(v) Base pairing
(vi) Proof reading and DNA repair
(vii) DNA polymerase attaches at Or site
Select the correct sequence of DNA replication.

• A. (vii), (iii), (i), (ii), (v), (iv), (vi)
• B. (iii), (i), (vii), (ii), (v), (iv), (vi)
• C. (vii), (i) ,(iii), (ii), (v), (iv), (vi)
• D. (i), (iii), (ii), (vii), (v), (iv), (vi)

Answer 1

The correct option is D (i), (iii), (ii), (vii), (v), (iv), (vi)

The process of formation of new DNA molecules from old DNA molecules is called replication of DNA. In this process, the two DNA strands seperate and exposed, activation of deoxyribonucleotides takes place, synthesis of RNA primer, DNA polymerase joins to the DNA templates, base pairing occurs, chian formation takes place, proof reading occurs.

So, the correct option is '(i), (iii), (ii), (vii), (v), (iv), (iv)'.
