What about DNA, specifically, determines the traits of an organism?
the order of bases
500
Semi-conservative is used to describe DNA because:
Each completed replicated strand contains one of the original strands of DNA and one new strand
500

600
DNA is _____ stranded; RNA is _____ stranded.
double; single
600
Why must DNA be replicated into an exact copy?
The DNA must be copied exactly so that the daughter cells get a complete and accurate copy of all genetic material.

The basic steps of DNA replication
1) Helicase unzips the helix
2) DNA polymerase adds new nucleotides to the original strand
3) Two identical DNA molecules are made.
