DNA Replication

What is the purpose of DNA Replication?

• to make identical copies of cells

• to make identical copies of DNA

• to make different types of RNA

• to make proteins used inside the cell

Where does DNA Replication occur inside eukaryotic cells?

• cytoplasm

• vacuole

• lysosome

• Golgi bodies

• nucleus

Where does DNA Replication occur inside prokaryotic cells?

• nucleoid

• vacuole

• lysosome

• Golgi bodies

• nucleus

When in the Cell Cycle does DNA Replication occur?

• S phase

• M phase

• Mitosis

• Interphase

• Cytokinesis

What is the goal of DNA Replication? (what must occur by the end of DNA Replication?)

• to create genetically identical copies of DNA molecules

• to create genetically different DNA molecules

• to create more cells

• none of these answers are true

Replicate the following strand of DNA: 
5' AAT CAT GGA 3'

• 3' AAT CAT GGA 5'

• 3' TTA GTA CCT 5'

• 3' UUA GUA CCU 5'

• 3' GGA TAU CUA 5'

The enzyme that unzips the DNA during DNA Replication is ....

• helicase

• DNA polymerase

• RNA polymerase

• ligase

• primase

DNA replication is described as SEMI-CONSERVATIVE, which 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

A scientist observes a base sequence of 5' AGC TAG CTA GCT 3'. Which of the following would be the complementary strand?

• 5' AGC TAG CTA GCT 3'

• 5' TTA AGG CCT TCC 3'

What is responsible for holding the two strands of the DNA double helix together?

• hydrogen bonds
• covalent bonds

• sugar-phosphate backbone

• ionic bonds
