The process of making a copy of a DNA molecule is called...

• DNA replication

• DNA recycling

• DNA duplication

• DNA polymerase

DNA Helicase and DNA Polymerase are alike in that both are

• nucleotides

• nucleic acids

• enzymes

• bases

DNA helicase's main function is to

• unwind the double helix of DNA

• add complementary base pairs to create a new DNA strand

• bind DNA fragments together

• none of the above

DNA must be replicated before...

• cell death

• making new cells

• digesting food

• making proteins

DNA replication is semi-conservative, which means that at the end of replication, each new DNA molecule is composed of...

• two new strands of DNA

• two original (old) strands of DNA

• either two new or two original strands of DNA

• one new strand and one original strand of DNA
