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 difference between the leading and lagging strands during DNA replication?

Back

The leading strand is synthesized continuously, while the lagging strand is synthesized in fragments.

Front

What is transcription in the context of protein synthesis?

Back

The process of copying a segment of DNA into RNA.
