DNA Replication Review

Front

What is DNA replication?

Back

The process by which a cell makes an exact copy of its DNA, resulting in two DNA molecules, each containing one original and one new strand.

Front

What is the result of DNA replication?

Back

2 DNA molecules that each contain a strand of the original.

Front

What percentage of each new DNA strand is derived from the original strand?

Back

50% of each new DNA strand is the old DNA.

Front

Where do mutations primarily occur?

Back

Mutations occur in DNA.

Front

What must happen first for DNA replication to occur?

Back

DNA must be unwound.

Front

Why does DNA replicate?

Back

To create another copy for the new cell.

Front

What enzyme is responsible for adding nucleotides during DNA replication?

Back

DNA polymerase.

Front

What are the two main stages of DNA replication?

Back

Initiation and elongation.

Front

What is the role of helicase in DNA replication?

Back

Helicase unwinds the DNA double helix.

Front

What is the significance of the leading and lagging strands in DNA replication?

Back

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