Front

What is the shape of DNA?

Back

DNA has a double helix shape, resembling a twisted ladder.

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

DNA stores and transmits genetic information that determines the traits of an organism.

Front

What are the building blocks of DNA?

Back

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

Front

What are the four nitrogenous bases in DNA?

Back

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

Front

How do the nitrogenous bases pair in DNA?

Back

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

Front

What is DNA replication?

Back

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

Front

Where does DNA replication occur in the cell?

Back

DNA replication occurs in the nucleus of the cell.

Front

What is a gene?

Back

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