DNA Replication

Front

What are Okazaki fragments?

Back

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

Front

On which strand of DNA do Okazaki fragments appear during DNA replication?

Back

Lagging strand.

Front

What does 'semi-conservative' mean in the context of DNA replication?

Back

Each new DNA molecule consists of one old (parent) strand and one new strand.

Front

Why is DNA replication said to occur during the S-phase of Interphase?

Back

The cell is about to divide and must have two identical copies of DNA for the new cells.

Front

What is the first action that occurs in DNA replication?

Back

DNA Helicase unwinds the original DNA strand.

Front

What is the role of DNA Helicase in DNA replication?

Back

It unwinds and unzips the DNA double helix.

Front

What is the function of RNA Primase in DNA replication?

Back

It lays down an RNA primer for new nucleotide bases.

Front

What does DNA Polymerase do during DNA replication?

Back

It builds new strands by bringing in new nucleotide bases.

Front

What is the role of DNA Ligase in DNA replication?

Back

It knits together fragments on the lagging strand.

Front

What is the significance of the S-phase in the cell cycle?

Back

It is the phase where DNA replication occurs, ensuring each daughter cell receives an identical set of DNA.
