Biology DNA Replication

Front

What direction is a new strand of DNA created during DNA replication?

Back

5' to 3' direction.

Front

What is the main reason for the difference in the way leading and lagging strands are synthesized?

Back

The antiparallel nature of the DNA strands.

Front

Which enzyme is responsible for joining fragments of the lagging strand?

Back

Ligase.

Front

True or False: The leading strand is synthesized continuously, while the lagging strand is synthesized discontinuously.

Back

True.

Front

What is the role of DNA polymerase in DNA replication?

Back

DNA polymerase synthesizes new DNA strands by adding nucleotides.

Front

What is helicase's function during DNA replication?

Back

Helicase unwinds the DNA double helix.

Front

Define 'antiparallel' in the context of DNA structure.

Back

Antiparallel refers to the opposite orientation of the two strands of DNA, running in 5' to 3' and 3' to 5' directions.

Front

What are Okazaki fragments?

Back

Short segments of DNA synthesized on the lagging strand during DNA replication.

Front

What is the significance of RNA primers in DNA replication?

Back

RNA primers provide a starting point for DNA synthesis.

Front

What is the function of topoisomerase in DNA replication?

Back

Topoisomerase relieves the tension in the DNA helix ahead of the replication fork.
