The new DNA made from the lagging strand is synthesized in the _________ direction

• 5' to 3'
• 3' to 5'

The new DNA on the leading strand is synthesized in the _________ direction

• 5' to 3'
• 3' to 5'

Small segments of DNA made on the lagging strand are called:

• Okazaki Fragments
• ERVs
• Transposable Elements
• Telomeres

The term used to describe DNA Replication is:

• Semi-Conservative
