DNA Replication

Front

What are Okazaki fragments?

Back

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

Front

On which strand are Okazaki fragments found?

Back

Lagging strand.

Front

What is the role of DNA ligase in DNA replication?

Back

Seals the gaps between Okazaki fragments.

Front

What enzyme helps helicase unzip DNA by relieving supercoiling?

Back

Topoisomerase.

Front

How do the leading and lagging strands differ in synthesis direction?

Back

The leading strand is synthesized into the replication fork, while the lagging strand is synthesized in the opposite direction.

Front

What does the term 'semi-conservative' model of DNA replication mean?

Back

Each DNA molecule after replication contains one original strand and one new strand.

Front

What is the function of DNA helicase?

Back

Unwinds the DNA double helix during replication.

Front

What is the role of DNA polymerase in DNA replication?

Back

Synthesizes new DNA strands by adding nucleotides complementary to the template strand.

Front

What is the significance of the 5' to 3' direction in DNA synthesis?

Back

DNA strands are synthesized in the 5' to 3' direction, meaning nucleotides are added to the 3' end.

Front

What is primase and its function in DNA replication?

Back

An enzyme that synthesizes a short RNA primer to initiate DNA synthesis.
