DNA Structure and Replication Practice

Front

What is DNA replication?

Back

The process of copying a DNA molecule to produce two identical DNA molecules.

Front

What happens to the DNA molecule during the first step of DNA replication?

Back

The DNA molecule is being unzipped and separated into two strands.

Front

Where does DNA replication occur in a cell?

Back

In the nucleus.

Front

True or False: DNA does not have to break apart to be copied.

Back

False.

Front

What enzyme is responsible for separating the DNA strands during replication?

Back

Helicase.

Front

What is the role of nucleotides in DNA replication?

Back

Nucleotides are the building blocks that are added to the existing DNA strands to form new strands.

Front

What is the function of ligase in DNA replication?

Back

Ligase joins the DNA strands together after replication.

Front

What are the two main steps of DNA replication?

Back

1. Unzipping of the DNA strands. 2. Adding new nucleotides to form new strands.

Front

What is the significance of complementary base pairing in DNA replication?

Back

It ensures that the new DNA strands are identical to the original strands.

Front

What happens to the original DNA strands after replication?

Back

They serve as templates for the synthesis of new strands.
