• To unzip DNA strands

What triggers the start of DNA replication at specific sites?

• The complete unwinding of the DNA helix

• The attachment of RNA primers

• The recognition of specific DNA sequences

• The presence of specific proteins

Which bases pair together in DNA?

• All bases pair randomly

• Adenine with Cytosine, Guanine with Thymine

• Adenine with Thymine, Guanine with Cytosine

• Adenine with Guanine, Cytosine with Thymine

Why is it important that DNA strands are anti-parallel?

• It prevents DNA replication

• It allows for the correct replication process

• It speeds up the replication process

• It has no impact on DNA replication

In which direction does DNA Polymerase build new DNA strands?

• Both 5' to 3' and 3' to 5'

• 3' to 5'

• Random direction

• 5' to 3'

What is the role of Ligase in DNA replication?

• To synthesize new DNA strands

• To glue DNA fragments together

• To unzip DNA strands

• To lay down RNA primers
