DNA and DNA Replication

Front

What is the primary function of DNA in living organisms?

Back

DNA serves as the blueprint for traits of all living things.

Front

Describe the structure of a DNA molecule.

Back

A DNA molecule is structured as a double helix.

Front

What are the products of DNA replication?

Back

DNA replication results in two DNA molecules, each with one new strand and one original strand.

Front

What type of bond joins nitrogenous bases in DNA?

Back

Nitrogenous bases are joined by hydrogen bonds.

Front

What is the correct order of DNA replication steps?

Back

The order of replication is 3, 4, 1, 2.

Front

What are the four nitrogenous bases found in DNA?

Back

The four nitrogenous bases in DNA are adenine (A), thymine (T), cytosine (C), and guanine (G).

Front

How do adenine and thymine pair in DNA?

Back

Adenine pairs with thymine through two hydrogen bonds.

Front

How do cytosine and guanine pair in DNA?

Back

Cytosine pairs with guanine through three hydrogen bonds.

Front

What is the role of DNA polymerase in DNA replication?

Back

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

Front

What is the significance of the antiparallel structure of DNA?

Back

The antiparallel structure allows for proper base pairing and replication of DNA.
