Front

What are the building blocks of DNA?

Back

The building blocks of DNA are nucleotides.

Front

What are the components of a nucleotide?

Back

A nucleotide is made up of a sugar (deoxyribose), a phosphate group, and a nitrogenous base.

Front

What are the four nitrogenous bases in DNA?

Back

The four nitrogenous bases in DNA are Adenine (A), Thymine (T), Cytosine (C), and Guanine (G).

Front

According to Chargaff's rule, which bases pair together in DNA?

Back

Adenine pairs with Thymine, and Cytosine pairs with Guanine.

Front

What forms the rungs of the DNA ladder?

Back

The rungs of the DNA ladder are formed by pairs of nitrogenous bases.

Front

What forms the sides of the DNA ladder?

Back

The sides of the DNA ladder are made up of alternating sugar and phosphate groups.

Front

What is the shape of the DNA molecule?

Back

The DNA molecule has a double helix shape.

Front

What is the function of DNA?

Back

DNA stores and transmits genetic information.

Front

What is the process of DNA replication?

Back

DNA replication is the process by which DNA makes a copy of itself before cell division.
