DNA

Front

What determines the code, or information, of a DNA molecule?

Back

The order (sequence) of the nitrogen bases.

Front

What are the building blocks of DNA?

Back

Nucleotides.

Front

What are the three components of a nucleotide?

Back

A phosphate group, a sugar (deoxyribose), and a nitrogen base.

Front

What is the structure of DNA?

Back

DNA is a double helix composed of two strands of nucleotides.

Front

What is the base pairing rule in DNA?

Back

Adenine pairs with Thymine, and Cytosine pairs with Guanine.

Front

What is the process of DNA replication?

Back

DNA replication is the process by which a DNA molecule makes a copy of itself.

Front

What is the result of DNA replication?

Back

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

Front

How does the amount of Adenine compare to Thymine in a DNA molecule?

Back

The amount of Adenine is always equal to the amount of Thymine.

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.

Front

What is the significance of the 5' and 3' ends of a DNA strand?

Back

They indicate the directionality of the DNA strand, which is important for replication and transcription.
