DNA Replication

Front

What is the process in which DNA makes an exact copy of itself?

Back

Replication

Front

Why is DNA replication called semi-conservative?

Back

Because it results in two identical molecules, each with one original strand and one new strand.

Front

If the template strand of DNA has the sequence AACC, what will the first four bases of the new DNA strand be?

Back

TTGG

Front

What does DNA replication result in?

Back

Two DNA molecules, each with one new strand and one original strand.

Front

What is the role of helicase in DNA replication?

Back

Helicase unwinds the DNA double helix to prepare for replication.

Front

What is the function of DNA polymerase?

Back

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

Front

What are the building blocks of DNA?

Back

Nucleotides, which consist of a sugar, a phosphate group, and a nitrogenous base.

Front

What are the four nitrogenous bases in DNA?

Back

Adenine (A), Thymine (T), Cytosine (C), and Guanine (G).

Front

What base pairs with Adenine in DNA?

Back

Thymine (T) pairs with Adenine (A).

Front

What is the significance of the 5' to 3' direction in DNA replication?

Back

DNA strands are synthesized in the 5' to 3' direction, meaning nucleotides are added to the 3' end of the growing strand.
