Why is DNA replication a semi-conservative process?

• it results in a a completely new strand of DNA and a strand made of only the original strand

• it results in two stands of DNA each composed of one new and one original strand

What is the function of the enzyme helicase in DNA replication?

• build a new strand of DNA

• break hydrogen bonds between paired nitrogen bases

• add a primer for replication to begin

• seal gaps in lagging strand
