DNA REPLICATION ANIMATION

CLICK HERE for an animation on DNA Replication.
QUESTIONS:
1. Why does DNA need to duplicate prior to cell division?
2. Why is DNA replication semiconservative?
3. Why is DNA a twisted ladder (double helix)

  1. The DNA in a cell that's about to divide needs to duplicate it's DNA so that when it divides, both of the daughter cells have the same amount of DNA. DNA is a double helix so that it can fit in the nucleus of a cell in our body.
