DNA & DNA Replication

Which sequence of DNA bases would pair with this partial strand

CAT TCA CTG?

• ATG TGA CAG

• TAC ACT GTC

• GTA AGT GAC

• CAT TCA CTG

The enzyme that unwinds the DNA to prepare for replication

• helicase
• replicase
• polymerase
• synthase

These pictures shows the different stages of replication. Place them in order from start to finish.

• 3, 4, 2, 1

• 3, 1, 4, 2

• 2, 1, 4, 3

• 3, 4, 1, 2

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 are the products of DNA Replication?

• 1 DNA Molecule

• 2 Identical DNA molecules, each with one new strand and one old strand

• 2 completely new DNA molecules

• 4 new molecules of DNA

Which enzyme is involved in the last step of DNA replication and proofs and then reseals the two strands?

• Ligase

• Polymerase

• Helicase

• Primase

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

What is the monomer of DNA?

• Amino acid

• Monosacchardie

• Glycerol + Fatty acid

• Nucleotide

Pick the correct Base-Pair rules for DNA.

• A pairs with T, G pairs with C

• A pairs with G, T pairs with C

• A pairs with C, T pairs with G

• There are no rules, bases can pair however
