Answer 1

if you have any doubt regarding question let me know if you are understand then give me thumb up.

this revealing the Ans- A poly neuclokide chain eis Synthesized by Copying Oy a complementary template Strand using CONA) In process, the duplex DNA is to locally inwound impairs template Stend and nucleotide and added to the 3 hydroxyl and growing stend by stemd by DNA polymerise. Hence answer will be option (C) nucleophilic atack of a 3'-on group al a nueckotide r - plosphorus # As th on anothers group,
