Cell Cycle and DNA Review

Place the steps of DNA replication in sequential order:

• 1, 2, 3, 4

• 3, 4, 2, 1

• 3, 2, 4, 1

• 2, 3, 4, 1

Why does DNA replicate?

• To create another copy for the new cell

• To create a duplicate copy in case the original gets damaged

• To create a new copy to replace the damaged original

DNA replication results in

• 2 completely new DNA molecules

• 2 DNA molecules that each contain a strand of the original

• 1 new DNA molecule and 1 old

• 1 new molecule of DNA

A DNA nucleotide contains all of the following, except...

• Deoxyribose

• Phosphate group

• Nitrogenous base

• Cholesterol

What is the shape of DNA?

• Double helix

• Triple helix

• Flat, bilayer

• Three-pronged rigid ladder
