What is the structure of DNA?

Back

DNA is a double helix formed by two strands of nucleotides twisted around each other.

Front

What are the building blocks of DNA?

Back

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

What is Chargaff's rule?

Back

Chargaff's rule states that in a DNA molecule, the amount of adenine equals thymine and the amount of cytosine equals guanine.

Where is DNA found in eukaryotic cells?

Back

In eukaryotic cells, DNA is primarily located in the nucleus.

Front

Who are Watson and Crick?

Back

James Watson and Francis Crick are scientists known for discovering the double helix structure of DNA.

Front

What role does the phosphate group play in DNA?

Back

The phosphate group forms the backbone of the DNA strand, linking the sugars of adjacent 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 DNA replication?

Back

DNA replication is the process by which a cell makes an exact copy of its DNA before cell division.

Front

What enzyme is responsible for DNA replication?

Back

DNA polymerase is the enzyme responsible for synthesizing new DNA strands during replication.
