Look at the image of DNA, notice there are lines between the nitrogen containing bases, what do those lines represent?

• Covalent Bonds

• Hydrogen Bonds

DNA is shaped like a...

• Pentagon

• Single Strand

• Double-Helix

• Circle

Why is DNA important?

• it is very small and very complicated
• it's in everything
• it serves as the blueprint for traits of all living things
• because we eat it every day for energy

Which organelle is DNA usually found in?

• cell membrane
• vacuole
• chloroplast
• nucleus

DNA replication results in two DNA molecules,

• each one with two original strands
• each one with two new strands
• each one with one new strand and one original strand
• one with two new strands and the other with two original strands

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

What is the RNA complimentary sequence to ATGCAT

• TACGTA

• UACGUA

• TACTGT

• AUGGTA
