DNA structure

Front

What is DNA?

Back

DNA (Deoxyribonucleic Acid) is the molecule that carries the genetic instructions for life.

Front

What are the building blocks of DNA?

Back

The building blocks of DNA are nucleotides.

Front

What are the three components of a nucleotide?

Back

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

Front

What are the four nitrogen bases in DNA?

Back

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

Front

How do nitrogen 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 shape of the DNA molecule is a double helix.

Front

What forms the backbone of the DNA structure?

Back

The backbone of the DNA structure is formed by deoxyribose (sugar) and phosphate.

Front

What is the function of DNA?

Back

The function of DNA is to store and transmit genetic information.

Front

What is a gene?

Back

A gene is a segment of DNA that contains the instructions for making a specific protein.

Front

What is replication in the context of DNA?

Back

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