Front

What is the role of DNA polymerase in DNA replication?

Back

It synthesizes new DNA strands by adding nucleotides complementary to the template strand.

Front

What is the function of helicase in DNA replication?

Back

It unwinds the DNA double helix.

Front

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

Back

They indicate the directionality of the DNA strand, which is crucial for replication and transcription.

Front

What is semi-conservative replication?

Back

It is the process where each new DNA molecule consists of one original strand and one newly synthesized strand.
