DNA Test Review - Honors Bio

The synthesis of a new double strand of DNA begins when the two strands of the original DNA

• are separated by the breaking of hydrogen bonds between nitrogen bases

• acts as a template

• attracts a nitrogen base

• destroys the entire genetic code

After DNA replication, the two DNA molecules that are made

• are opposite

• are identical

• leave the nucleus

• cannot replicate again
