DNA Replication

What is the primary purpose of DNA replication?

• To create new cells.

• To produce more DNA.

• To direct cellular functions.

• To code for genetic traits.

In which cellular organelle does DNA replication primarily occur in eukaryotic cells?

• Cytoplasm

• Mitochondria

• Nucleus

• Ribosomes

Which enzyme is responsible for unwinding and separating the two strands of DNA during replication?

• DNA Polymerase

• Primase

• Ligase

• Helicase

What is the function of Primase during DNA replication?

• To build new DNA strands.

• To prevent DNA supercoiling.

• To create an RNA primer for DNA Polymerase.

• To glue DNA fragments together.

What does it mean for DNA strands to be antiparallel?

• They run in the same direction, both 5' to 3'.

• One strand runs 5' to 3', and the other runs 3' to 5'.

• They are parallel but have different base sequences.

• They are not parallel and do not interact.

In which direction does DNA polymerase synthesize a new DNA strand?

• 3' to 5'

• 5' to 3'

• Both 3' to 5' and 5' to 3' simultaneously

• Randomly, depending on available nucleotides

Why is the lagging strand synthesized in fragments during DNA replication?

• Helicase unwinds DNA too quickly for continuous synthesis.

• Primase can only place primers in short bursts.

• DNA polymerase can only add nucleotides to the 3' end of a growing strand.

• Ligase needs gaps to join the new DNA segments.

What is the term for DNA replication where each new DNA molecule consists of one original strand and one newly synthesized strand?

• Conservative replication

• Dispersive replication

• Semi-conservative replication

• Progressive replication
