Answer:
Option (b).
Explanation:
Replication involves formation of daughter DNA strands by using information present in parent DNA, with the help of DNA polymerase enzyme.
It takes place during the time of cell division as daughter DNA molecules are provided to new daughter cells. During DNA replication, adenine pairs with thymine and guanine pairs with cytosine. It takes place inside the nucleus.
Transcription involves formation of mRNA molecules with the help of template DNA and RNA polymerase enzyme. It occurs during the process of protein synthesis. During DNA transcription, adenine pairs with uracil, instead of thymine and guanine pairs with cytosine. It also takes place inside the nucleus.
Thus, the correct answer is option b.
