What are the three parts of a nucleotide?
A phosphate group, a sugar, and a base
300
What are the "rungs" of the DNA ladder made of?
Bases

How many different bases make up DNA?
four

How does DNA replicate?
The strands separate, a new strand is built complementary to the original, and we are left with two new double strands. 1/2 made from old DNA, 1/2 made from new DNA

What did Crick and Watson call the 3D structure of DNA?
Double Helix

What was Rosalind Franklin known for?
X-ray crystalography photographs of DNA

Where is DNA found?
In the nucleus of the cell

How far do we need to zoom in on a cell to find the DNA?
Into the nucleus, into the chromosome that is made up of DNA

Why does DNA need to double before mitosis can occur?
Because each cell needs a copy of DNA - if it didn't double and the cell divided, one cell would not have any DNA and the cell would die
