Chromosomes are made of these.
What are proteins and DNA?
300
Genetically altering plants, repairing damaged genes, and manufacturing proteins are all examples of ______
What is genetic engineering?

How does a DNA molecule make a copy of itself? (3 steps)
DNA splits down the middle, separating the paired-bases. Bases then pair up with other nucleotides, (A,T &C,G). This creates two identical DNA molecules.
