Front

What are nucleotides?

Back

Nucleotides are the building blocks of DNA, consisting of a sugar, a phosphate group, and a nitrogenous base.

What are the four nitrogenous bases in DNA?

Back

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

Front

How do the nitrogenous bases pair in DNA?

Back

Adenine pairs with Thymine (A-T) and Cytosine pairs with Guanine (C-G).

Front

What is the shape of the DNA molecule?

Back

The DNA molecule has a double helix shape.

Front

What role does DNA play in heredity?

Back

DNA carries genetic information that is passed from parents to offspring.
