DNA REPLICATION WARM-UP:

1.) What is DNA Replication? the process where DNA Molecules make copies of themselves, so that when a cell divides, each new cell will have an exact copy of the original cell's DNA.
2.) What are the sides of the DNA Molecule made of? The sides of a DNA molecule are made up of alternating Sugars & Phosphates.
3.) What are the Rungs of the DNA Molecule made of? The rungs of a DNA molecule are made up of Nitrogen Bases.
4.) What are the 4 Nitrogen Bases? - 4 Nitrogen Bases = Adenine (A), Thymine (T), Cytosine (C), and Guanine (G)
5.) Which Nitrogren Bases pair up during DNA Replication?

Adenine & Thymine always pair.

A-T

Cytosine & Guanine always pair.

C-G

6.) What are the Steps for DNA Replication?

Steps for DNA Replication:

1.) DNA Molecule Unzips.

2.) DNA Molecule separates into 2 halves.

3.) Free-floating Nitrogen Bases pair up with each half of the DNA Molecule.

4.) 2 DNA Molecules have been created with the same genetic code as the original DNA Molecule.
