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 and separates the double-stranded DNA.

Front

What is the significance of the antiparallel structure of DNA?

Back

It allows for proper base pairing and replication.

Front

What is a mutation in the context of DNA?

Back

A change in the nucleotide sequence of DNA.
