DNA Replication

Front

What are SSB (single stranded binding proteins)?

Back

Proteins that help hold the DNA strands apart during replication, preventing them from recoiling.

Front

What is the role of helicase in DNA replication?

Back

Helicase is the enzyme responsible for unzipping the double helix of DNA.

Front

What does topoisomerase do during DNA replication?

Back

Topoisomerase prevents hypercoiling by relieving the strain caused by the uncoiling at the replication fork.

Front

What is the function of DNA ligase?

Back

DNA ligase is the enzyme that fixes the Okazaki fragments on the lagging strand by joining them together.

Front

What do 3' and 5' refer to in DNA structure?

Back

They refer to the direction in which the nucleotides are oriented in the DNA strand.

Front

What is the role of DNA polymerase?

Back

DNA polymerase is the enzyme that synthesizes new DNA strands by adding nucleotides complementary to the template strand.

Front

What is the significance of the RNA primer in DNA replication?

Back

The RNA primer provides a starting point for DNA polymerase to begin synthesis of the new DNA strand.

Front

What are Okazaki fragments?

Back

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

Front

How does the structure of DNA contribute to its replication?

Back

The double helix structure allows for the separation of strands, enabling each strand to serve as a template for new DNA synthesis.

Front

What is the difference between leading and lagging strands?

Back

The leading strand is synthesized continuously, while the lagging strand is synthesized in short segments (Okazaki fragments).
