Structure of DNA

Front

What is the structure of DNA?

Back

DNA is a double helix made up of two strands that wind around each other, consisting of nucleotides.

Front

What are the four nitrogen bases in DNA?

Back

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

Front

What does Adenine bond with in DNA?

Back

Adenine bonds with Thymine.

Front

What does Guanine bond with in DNA?

Back

Guanine bonds with Cytosine.

Front

What is a nucleotide?

Back

A nucleotide is the basic building block of DNA, consisting of a phosphate group, a sugar (deoxyribose), and a nitrogen base.

Front

What is the role of the phosphate group in DNA?

Back

The phosphate group forms the backbone of the DNA structure, linking the sugar molecules.

Front

What is deoxyribose sugar?

Back

Deoxyribose sugar is the sugar component of DNA nucleotides.

Front

What is the function of DNA?

Back

DNA stores genetic information and provides instructions for the development and functioning of living organisms.

Front

What is complementary base pairing?

Back

Complementary base pairing refers to the specific pairing of nitrogen bases: Adenine with Thymine and Guanine with Cytosine.

Front

What is the significance of the double helix structure?

Back

The double helix structure allows DNA to be stable and compact, while also enabling replication and transcription.
