What is the result of DNA replication?

• 2 copies of DNA with identical genetic code

• 2 copies of DNA with different genetic codes

• 1 identical copy of DNA. The old copy is destroyed.

• 1 copy of DNA with new genes. the old copy is destroyed.

Why is DNA replication necessary?

• To create new DNA for new cells

• To help a cell work more efficiently

• To reduce the number of mutations in DNA

• To create proteins for the cell

Which of the following best describes the make-up of newly made DNA strands after replication??

• Strand 1 = 100% new

  Strand 2 = 100% old

• Strand 1 = 75 % new and 25% old

  Strand 2 = 25% new and 75% old

• Strand 1 = 50% new and 50% old

  Strand 2 = 50% new and 50% old

• Each strand has a random mixture of old and new DNA
