Structure of DNA

Front

What is DNA?

Back

DNA (Deoxyribonucleic Acid) is a complex molecule that carries genetic information defining an organism's traits. It is stored in the nucleus of cells.

Front

What shape does DNA have?

Back

The shape of DNA is known as a double helix, which resembles a twisted ladder.

Front

What pairs with Adenine in DNA?

Back

In DNA, Adenine pairs with Thymine.

Front

What is the function of DNA?

Back

DNA contains the instructions needed for an organism to develop, survive, and reproduce.

Front

What are the building blocks of DNA?

Back

The building blocks of DNA are nucleotides, which consist of a nitrogen base, a phosphate group, and a deoxyribose sugar.

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

What is a nucleotide?

Back

A nucleotide is the basic structural unit of DNA, composed of a nitrogen base, a phosphate group, and a deoxyribose sugar.

Front

What is the role of the phosphate group in DNA?

Back

The phosphate group in DNA helps to form the backbone of the DNA structure, linking the sugar molecules together.

Front

What is the significance of the sequence of bases in DNA?

Back

The sequence of bases in DNA determines the genetic information and instructions for building proteins.

Front

How do DNA bases pair with each other?

Back

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