DNA Replication 24

Front

What base pairs with thymine?

Back

Adenine

Front

What is the first step in DNA replication?

Back

Helicase breaks the hydrogen bonds between the bases to split the original strand.

Front

What is the second step in DNA replication?

Back

Primase marks where to start building the new strand of DNA.

Front

What is the fourth step in DNA replication?

Back

There are fragments left on the lagging strand when DNA polymerase is done.

Front

What base pairs with guanine?

Back

Cytosine

Front

What is the role of DNA Polymerase in DNA replication?

Back

DNA Polymerase starts to attach new nucleotides to the original strand.

Front

What is the function of Ligase in DNA replication?

Back

Ligase glues together the fragments on the lagging strand of DNA.

Front

What is the role of Helicase in DNA replication?

Back

Helicase unwinds the DNA double helix by breaking the hydrogen bonds between the base pairs.

Front

What are Okazaki fragments?

Back

Short sequences of DNA nucleotides synthesized on the lagging strand during DNA replication.

Front

What is the significance of Primase in DNA replication?

Back

Primase synthesizes a short RNA primer to provide a starting point for DNA synthesis.
