NGSS.HS-LS3-2

Place the following in sequential order
1. Recoil
2. Straightens the double helix
3. Breaks Hydrogen bonds
4. Adds Free nucleotides

• 1, 2, 3, 4
• 3, 4, 2, 1
• 3, 2, 4, 1
• 2, 3, 4, 1

What will the first four bases of the new DNA strand look like if copying the template strand?

• TGGT
• ACCA
• GTTG
• CAAC

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

Enzyme that connects the DNA to the backbone (glues)

• Ligase

• Polymerase

• Helicase

• Primase

Enzyme that breaks hydrogen bonds (unzips)

• Ligase

• Polymerase

• Primase

• Helicase
