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 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 is a nucleotide?

Back

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

Front

What is a gene?

Back

A gene is a section or piece of DNA that contains the instructions for making a specific protein or trait.

Front

What is the role of nitrogen bases in DNA?

Back

Nitrogen bases (adenine, thymine, cytosine, guanine) pair together to form the rungs of the DNA ladder, encoding genetic information.

Front

What is the structure of DNA?

Back

DNA has a double helix structure, resembling a twisted ladder, with two strands running in opposite directions.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains deoxyribose sugar, while RNA is single-stranded and contains ribose sugar.

Front

Where is DNA located in a cell?

Back

DNA is primarily located in the nucleus of eukaryotic cells.

Front

What is the function of DNA?

Back

The function of DNA is to store and transmit genetic information that guides the development and functioning of living organisms.

Front

What is a chromosome?

Back

A chromosome is a long, continuous thread of DNA that contains many genes and is found in the nucleus of cells.
