A piece of DNA with the sequence 5\' CAATCGAT 3\' is being replicated. What will the new sequence be?

5\' GTTAGCTA 3\'

3\' CAATCGAT 5\'

3\' GUUAGCUA 5\'

5\' CAATCGAT 3\'

3\' GTTAGCTA 5\'

Solution

Ans option e 3\' GTTAGCTA 5\'

Replication of DNA produces complimentary strand of opposite polarity.

So the polarity must be 3\' - 5\' for 5\'- 3\' strand.

And nucleotides, G for C, T for A, A for T and C for G
