What is DNA replication?

The process of making a copy of DNA

The process of dividing a cell into two daughter cells

The process of making a copy of RNA

The process of translating DNA into proteins

Is the DNA made during DNA replication an exact copy of the original DNA?

No, it is a completely different sequence

No, it is a similar but not exact copy

Yes, but it only copies half of the original DNA

What does "semiconservative" mean in the context of DNA replication?

Each DNA molecule consists of one original strand and one new strand.

Each DNA molecule is copied without conserving the original strands.

Each DNA molecule consists of two new strands.

Each DNA molecule is conserved without any replication.

What does the semiconservative model of DNA replication imply?

Each new DNA molecule consists of one original strand and one new strand.

Each new DNA molecule consists of two new strands.

Each new DNA molecule is entirely original, without any new strands.

The original DNA molecule is conserved while an entirely new molecule is synthesized.

Why does the nature of the bonds between DNA strands make it easy to replicate?

Because the bonds are non-polar

Because the bonds are permanent

What is the function of Helicase in DNA replication?

It adds nucleotides and proofreads

It copies DNA entirely on its own

What role does DNA Polymerase play in DNA replication?

It adds nucleotides and proofreads

What is the function of the enzyme helicase during DNA replication?

It "unzips" or separates the two strands of DNA.

It adds nucleotides to the new DNA strand.

It links together the pieces of new DNA.

It creates the initial RNA primer.

What role does DNA polymerase play in DNA replication?

It adds the nucleotides of the new strands using the old strand as a template.

It separates the two strands of DNA.

It links together the pieces of new DNA.

It prevents the DNA strands from rejoining.

What is the role of ligase in DNA replication?

It links together the pieces of new DNA.

It adds nucleotides to the new DNA strand.

It "unzips" or separates the two strands of DNA.

It creates the initial RNA primer.

What is the function of the enzyme labeled "1st Helicase" in DNA replication?

To add new nucleotides to the growing DNA strand

To seal the nicks in the sugar-phosphate backbone

To proofread and correct errors in DNA synthesis

Which enzyme is labeled as "2nd DNA Polymerase" in the diagram?

The enzyme responsible for adding free nucleotides to the new DNA strand

The enzyme responsible for unwinding the DNA double helix

The enzyme responsible for sealing nicks in the DNA strand

The enzyme responsible for introducing supercoils into DNA

What is the role of the enzyme labeled "3rd Ligase" in the diagram?

To seal the nicks in the sugar-phosphate backbone

To add new nucleotides to the growing DNA strand

To introduce supercoils into DNA
