A_DNA and DNA Replication

_________ unwinds DNA molecule

The enzyme responsible for making the DNA molecule is

• Ligase
• Helicase
• RNA polymerase
• DNA polymerase

DNA made during DNA Replication is semi-conservative. What does this mean?

• Each new DNA molecule contains two old strands.
• DNA replication is semi-conservative because each new DNA molecule contains one old strand and one new strand.
• DNA replication results in two identical strands only.
• DNA replication is conservative, keeping both strands intact.

What is the purpose of DNA Replication?

• To repair damaged proteins.
• To create energy for the cell.
• The purpose of DNA replication is to ensure that each daughter cell receives an identical copy of the DNA.
• To synthesize carbohydrates for metabolism.
