DNA Replication

Front

What is the role of Helicase in DNA replication?

Back

Helicase is the enzyme responsible for unwinding the DNA double helix prior to replication.

Front

What does DNA polymerase do during DNA replication?

Back

DNA polymerase adds free nucleotides to the growing DNA strand during replication.

Front

In which direction does DNA replication occur?

Back

DNA replication runs from 5' to 3' direction.

Front

What does it mean that DNA strands are antiparallel?

Back

Antiparallel means that the two strands of DNA run in opposite directions.

Front

How does DNA polymerase replicate the leading strand?

Back

DNA polymerase replicates the leading strand continuously.

Front

What is the function of DNA Ligase in DNA replication?

Back

DNA Ligase joins Okazaki fragments on the lagging strand, sealing nicks in the sugar-phosphate backbone.

Front

What are Okazaki fragments?

Back

Okazaki fragments are short sequences of DNA synthesized on the lagging strand during DNA replication.

Front

What is the difference between the leading strand and the lagging strand?

Back

The leading strand is synthesized continuously, while the lagging strand is synthesized in short fragments.

Front

What is the significance of free nucleotides in DNA replication?

Back

Free nucleotides are the building blocks that DNA polymerase uses to synthesize new DNA strands.

Front

What is the role of RNA primers in DNA replication?

Back

RNA primers provide a starting point for DNA polymerase to begin synthesis.
