DNA Replication

Front

What is DNA replication?

Back

DNA replication is the process by which a cell makes an exact copy of its DNA, resulting in two identical DNA molecules.

Front

What percent of each new DNA strand is the old strand?

Back

Half of each new DNA strand is the old DNA.

Front

What are the four nitrogen bases in DNA?

Back

The four nitrogen bases in DNA are adenine, thymine, cytosine, and guanine.

Front

What shape does a DNA molecule have?

Back

A DNA molecule has a double helix shape.

Front

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

Back

'Semi-conservative' means that each new DNA molecule consists of one old strand and one newly synthesized strand.

Front

What base pairs with adenine in DNA?

Back

Thymine pairs with adenine in DNA.

Front

What base pairs with cytosine in DNA?

Back

Guanine pairs with cytosine in DNA.

Front

What is the role of DNA polymerase in DNA replication?

Back

DNA polymerase is the enzyme that synthesizes new DNA strands by adding nucleotides complementary to the template strand.

Front

What is the function of ligase in DNA replication?

Back

Ligase is the enzyme that joins Okazaki fragments on the lagging strand during DNA replication.

Front

What is the significance of the origin of replication?

Back

The origin of replication is the specific location on the DNA where replication begins.
