Front

What are the base pairing rules in DNA?

Back

Adenine pairs with thymine, and cytosine pairs with guanine.

Front

What is the significance of the 5' and 3' ends of DNA strands?

Back

They indicate the directionality of the DNA strands, which is crucial for replication.

Front

What is the function of helicase in DNA replication?

Back

It unwinds the double helix, separating the two strands of DNA.
